ASoC: cros_ec_codec: Add endianness flag in i2s_rx_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. The i2s_rx component 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.
