drm/amd/display: Rename bytes_pp to the correct bits_pp

[Why]
Struct dcn_dsc_state is used for reading current state
and parameters of DSC on a pipe, the target rate parameter
uses bytes per pixel even though its reading BITS_PER_PIXEL
register.

[How]
Changing it to Bits Per Pixel for consistency.
