drm/msm/dp: Remove dead code related to downstream cap info

Browse source

We read the downstream port count and capability info but never use it
anywhere. Remove 'ds_port_cnt' and 'ds_cap_info' and any associated code
from this driver. Fold the check for 'dfp_present' into a call to
drm_dp_is_branch() at the one place it is used to get rid of any member
storage related to downstream ports.
