drm/msm/dp: employ bridge mechanism for display enable and disable
Currently the msm_dp_*** functions implement the same sequence which would
happen when drm_bridge is used. hence get rid of this intermediate layer
and align with the drm_bridge usage to avoid customized implementation.

Changes in v2:
-- revise commit text
-- rename dp_bridge to msm_dp_bridge
-- delete empty functions
Changes in v3:
-- replace kzalloc() with devm_kzalloc()
-- replace __dp_display_enable() with dp_display_enable()
-- replace __dp_display_disable() with dp_display_disable()
Changes in v4:
-- msm_dp_bridge_init() called from msm_dp_modeset_init() same as dsi
Changes in v5:
-- delete attach, mode_fixup and pre_enable from dp_bridge_ops
Changes in v6:
-- rebase on msm-next-plus-fixes branch
