drm/amd/display: Add debug option to override DSC target bpp increment
[why]
It's required for debug purposes.
[how]
Add a dsc_bpp_increment_div debug option that overrides DPCD
BITS_PER_PIXEL_INCREMENT value. The value dsc_bpp_increment_div should
be set to is the one after parsing, i.e. it could be 1, 2, 4, 8 or 16
(meaning 1pix, 1/2pix, ..., 1/16pix).
