drm/dsc: fix drm_edp_dsc_sink_output_bpp() DPCD high byte usage
[ Upstream commit 13525645e2246ebc8a21bd656248d86022a6ee8f ]
The operator precedence between << and & is wrong, leading to the high
byte being completely ignored. For example, with the 6.4 format, 32
becomes 0 and 24 becomes 8. Fix it, and remove the slightly confusing
and unnecessary DP_DSC_MAX_BITS_PER_PIXEL_HI_SHIFT macro while at it.
