[PATCH 04/38] ASoC: cs4270: Remove redundant big endian formats

The CODEC already provides the endianness flag on its
snd_soc_component_driver structure, specifying it is ambivalent
to endian. The core will expand the formats to cover both
endian types, as such remove the redundant specification of both
endians.
