Subject: drm/amd/display: Rename bytes_pp to the correct bits_pp
Git-commit: 5e061a4d020380566365e8aa8f629bbd200e9708
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
[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.
