Adds the OV5642 parallel-bus sensor, and the OV5640 MIPI CSI-2 sensor.
Both hang off the same i2c2 bus, so they require different (and non-
default) i2c slave addresses.
The OV5642 connects to the parallel-bus mux input port on ipu1_csi0_mux.
The OV5640 connects to the input port on the MIPI CSI-2 receiver on
mipi_csi.
The OV5642 node is disabled temporarily while the subdev driver is
cleaned up and submitted later.

This makes the structure of Sabre Lite board files the same
as Sabre SD board files so that they are easier to compare.
By this, I mean that the majority of the file imx6q-sabrelite.dts
is moved to imx6qdl-sabrelite.dtsi so that both imx6q-sabrelite.dts
and imx6dl-sabrelite.dts can include it.
Now Sabre Lite has support for Dual Lite/Solo
processors.

We must specify the value of audmux pinctrl if we want to use pinctrl_pm().
Thus change bypass value 0x80000000 to what we exactly need.
This patch also seperately unset PUE bit for TXD so that IOMUX won't pull
up/down the pin after turning into tristate. When we use SSI normal mode to
playback monaural audio via I2S signal, there'd be a pulled curve occur to
its signal at the second slot if setting PUE bit for TXD. And it will make
the second channel to play a constant noise. So by keeping the signal level
in the second slot, we can get a constant high level signal (-1) or a low
level one (0).

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts. However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected. This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board. It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.
The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral. Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

The CLKO is widely used by imx6q board designs to clock audio codec.
Since most codecs accept 24 MHz frequency, let's initially set up CLKO
with OSC24M (cko <-- cko2 <-- osc). Then those board specific CLKO
setup for audio codec can be removed.
The board dts files also need an update on cko reference in codec node.

The imx6q and imx6dl are two pin-to-pin compatible SoCs. The same board
design can work with either chip plugged into the socket, e.g. sabresd
and sabreauto boards.
We currently define pin groups in imx6q.dtsi and imx6dl.dtsi
respectively because the pad macro names are different between two
chips. This brings a maintenance burden on having the same label point
to the same pin group defined in two places.
The patch replaces prefix MX6Q_ and MX6DL_ with MX6QDL_ for both SoCs
pad macro names. Then the pin groups becomes completely common between
imx6q and imx6dl and can just be moved into imx6qdl.dtsi, so that the
long term maintenance of imx6q/dt pin settings becomes easier.
Unfortunately, the change brings some dramatic diff stat, but it's all
about DTS file, and the ultimate net diff stat is good.

Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function. Every time a new imx SoC support is
added, we need to add such a big mount of data. With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.
With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.
The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.
As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

Replace /include/ (dtc) with #include (C pre-processor) for all imx DT
files, so that gcc -E handles the entire include tree, and hence any of
those files can #include some other file e.g. for constant definitions.
This allows future use of #defines and header files in order to define
names for various constants, such as pinctrl settings. Use of those
features will increase the readability of the device tree files.

Major differences between imx6dl and imx6q:
* Dual vs. Quad cores
* single vs. dual IPU
* 128 vs. 256 KB OCRAM
* imx6q: ECSPI5, OpenVG (GC355), SATA
* imx6dl: I2C4, PXP, EPDC, LCDIF
* iomuxc/pads definition

i.MX6 Quad and i.MX6 DualLite is similar enough to share one dtsi
file, so rename imx6q.dtsi to imx6qdl.dtsi preparing for the addition
of imx6dl support.
Another member of i.MX6 series i.MX6 SoloLite is different enough
from the other two, so it will stand as a separate dtsi. That's why
we rename to imx6qdl.dtsi not imx6.dtsi.

It really becomes an maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.
Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx6q client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.
