ASoC: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ASoC: mt6351: Add endianness flag in snd_soc_component_driver

The endianness flag is used on the CODEC side to specify an
ambivalence to endian, typically because it is lost over the hardware
link. This device receives audio over an I2S DAI and as such should
have endianness applied.

As the core will now expand the formats to cover both endian types,
remove the redundant manual specification of both.

ASoC: fix return value check in mt6351_codec_driver_probe()

In case of error, the function dev_get_regmap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
