drm/i915/display: Store compressed bpp in U6.4 format
DSC parameter bits_per_pixel is stored in U6.4 format.
The 4 bits represent the fractional part of the bpp.
Currently we use compressed_bpp member of dsc structure to store
only the integral part of the bits_per_pixel.
To store the full bits_per_pixel along with the fractional part,
compressed_bpp is changed to store bpp in U6.4 formats. Intergral
part is retrieved by simply right shifting the member compressed_bpp by 4.
v2:
-Use to_bpp_int, to_bpp_frac_dec, to_bpp_x16 helpers while dealing
with compressed bpp. (Suraj)
-Fix comment styling. (Suraj)
v3:
-Add separate file for 6.4 fixed point helper(Jani, Nikula)
-Add comment for magic values(Suraj)
v4:
-Fix checkpatch warnings caused by renaming(Suraj)
v5:
-Rebase.
-Use existing helpers for conversion of bpp_int to bpp_x16
and vice versa.
