drm/bridge: tc358767: Change tc_ prefix to tc_edp_ for (e)DP specific…

… functions

These functions are specific to (e)DP output initialization and
operation, add specific tc_edp_ prefix to those functions to
discern them from DPI output functions that will be added later
in this series. No functional change.
