The node names should be generic and SPI NOR dtschema expects "flash".

Boards based on imx28 have duplicate memory nodes:
- One coming from the board dts file: memory@
- One coming from the imx28.dtsi file.
Fix the duplication by removing the memory node from the dtsi file
and by adding 'device_type = "memory";' in the board dts.

dtc has new checks for SPI buses. Fix the warnings in node names and
unit-addresses.
There's over 100 warnings for FSL boards, a few examples:
arch/arm/boot/dts/imx28-duckbill-2-spi.dtb: Warning (spi_bus_bridge): /apb@80000000/apbh@80000000/ssp@80014000: node name for SPI buses should be 'spi'
arch/arm/boot/dts/imx53-ppd.dtb: Warning (spi_bus_bridge): /soc/aips@50000000/spba@50000000/ecspi@50010000: node name for SPI buses should be 'spi'
arch/arm/boot/dts/imx6dl-colibri-eval-v3.dtb: Warning (spi_bus_reg): /soc/aips-bus@2000000/spba-bus@2000000/spi@2014000/mcp251x@1: SPI bus unit address format error, expected "0"

Fix the following warnings from dtc by adding the unit name to memory
nodes:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
Converted using the following command:
perl -p0777i -e 's/memory \{\n\t\treg = \<0x+([0-9a-f])/memory\@$1$\0000000 \{\n\t\treg = <0x$1/m' `find ./arch/arm/boot/dts -name "imx*"`
The files below were manually fixed:
-imx1-ads.dts
-imx1-apf9328.dts
-imx6q-pistachio.dts

The pins have nothing todo with the phy layer. We better rename them, so
it gets clear they are routed to the ehci core not to any phy.

The device tree specification recommends that generic name should be
used for nodes. So instead of naming those fixed regulator nodes
arbitrarily, let's use the generic name 'regulator@num' for those nodes.

Convert mx23/mx28 dts filed to use the pinctrl header files.
NOTE: During automatic conversion of these files to use the pinconfig
definitions an inconsistency has been found in:
arch/arm/boot/dts/imx28-apx4devkit.dts
According to the comment the function for pad SSP2_SS0 should have
been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131
represents: MX28_PAD_SSP2_SS0__AUART3_TX
I used the later (though probably wrong) definition because that's
what is actually being used in the DTB.

Slow down the I2C clock speed on M28 and SPS1 as it turns out the
I2C block in i.MX28 can not operate stable enough with the bus
running at 400kHz. Note that the driver used by Freescale runs
the bus at 250kHz when 400kHz speed is selected, but the mainline
Linux kernel runs the bus at actual 400kHz and that's where it is
occasionally unstable. Play safe and run the bus at 100kHz.
