drm/msm/dp: use the eDP bridge ops to validate eDP modes
The eDP and DP interfaces shared the bridge operations and
the eDP specific changes were implemented under is_edp check.
To add psr support for eDP, we started using a new set of eDP
bridge ops. We are moving the eDP specific code in the
dp_bridge_mode_valid function to a new eDP function,
edp_bridge_mode_valid under the eDP bridge ops.
