drm/i915/dp: Account with pipe joiner max compressed BPP limit for DP-MST and eDP

The pipe joiner maximum compressed BPP must be limited based on the pipe
joiner memory size and BW, do that for all DP outputs by adjusting the
max compressed BPP value already in
intel_dp_compute_config_link_bpp_limits() (which is used by all output
types).

This way the BPP doesn't need to be adjusted in
dsc_compute_compressed_bpp() (called for DP-SST after the above limits
were computed already), so remove the adjustment from there.
