This driver uses the consumer API, so include clk.h explicitly
instead of impliclty through the provider API.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the includes here because these are
a provider drivers.

The error paths in this file leak memory and mappings and test
for pointers being valid after dereferencing them. Fix these
problems and properly free resources on errors. Fix some
stylistic things too like using sizeof(*ptr) and fitting more
code on a single line. Note that we don't unregister clocks here.
That needs a clk_composite_unregister() API that we don't have
right now.

Currently it is not possible to use HDMI and LVDS at the same time on a
imx6dl-sabresd board.
Fix this usecase by setting IMX6QDL_CLK_PLL3_PFD1_540M to 540MHz and
also by setting it as the parent of IMX6QDL_CLK_IPU1_SEL.
Based on the configuration done in the FSL kernel.

Remove useless ifdefs around function prototypes to silence the

On the MT8173 the clocks are provided by different units. To enable
the critical clocks we must be sure that all parent clocks are already
registered, otherwise the parents of the critical clocks end up being
unused and get disabled later. To find a place where all parents are
registered we try each time after we've registered some clocks if
all known providers are present now and only then we enable the critical
clocks

The dwmac ethernet controller on the rk3288 supports phys connected
via rgmii and rmii. With rgmii phys it is expected that the mac clock
is provided externally while with rmii phys the clock can be external
but also generated from the plls. In the later case it of course needs
be at 50MHz, which gets set from the dwmac_rk driver.
As most devices use a rgmii phy it never surfaced so far that the mac
clk mux, doesn't go up one lever to the pll clock in the rmii case with
internal clock generation, as it is missing the CLK_SET_RATE_PARENT flag,
and thus will not set the correct frequency in most cases.
