[PATCH v4 4/8] drm/msm/dp: move parser->parse() and dp_power_client_init() to probe

[Kuogee Hsieh]

Move parser->parse() and dp_power_client_init() from dp_display_bind()
to dp_display_probe() in preparation of adding pm_runtime framework
at next patch.

Changes in v4:
-- split this patch out of "incorporate pm_runtime framework into DP driver" patch
