drm/msm/dp: move parser->parse() and dp_power_client_init() to probe
Original both parser->parse() and dp_power_client_init() are done at
dp_display_bind() since eDP population is done at binding time.
In the preparation of having eDP population done at probe() time,
move both function from dp_display_bind() to dp_display_probe().
Changes in v6:
-- move dp_power_client_deinit() to remove()
Changes in v5:
-- explain why parser->parse() and dp_power_client_init() are moved to
probe time
-- tear down sub modules if failed
Changes in v4:
-- split this patch out of "incorporate pm_runtime framework into DP
driver" patch
