ASoC: tlv320adc3xxx: Add endianness flag in snd_soc_component_driver

Browse Source 
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.

A fixup is also required to use the width directly rather than relying
on the format in hw_params, now both little and big endian would be
supported.
