drm: bridge/dw_hdmi: avoid enabling interface in mode_set
On a mode set, DRM makes the following sequence of calls:
* for_each_encoder
* bridge mode_fixup
* encoder mode_fixup
* crtc mode_fixup
* for_each_encoder
* bridge disable
* encoder prepare
* bridge post_disable
* disable unused encoders
* crtc prepare
* crtc mode_set
* for_each_encoder
* encoder mode_set
* bridge mode_set
* crtc commit
* for_each_encoder
* bridge pre_enable
* encoder commit
* bridge enable
dw_hdmi enables the HDMI output in both the bridge mode_set() and also
the bridge enable() step. This is duplicated work - we can avoid the
setup in mode_set() and just do it in the enable() stage. This
simplifies the code a little.
