Enabling the support of same in DRM layer for fine grained panel control. Some DSI controller/panels require making SOC specific device ready changes in between the panel power ON and sending the OTP sequences. This patch introduces drm_panel_power_on which can be used to decouple panel power ON and OTP. Earlier both operations were being done as part of drm_panel_prepare.
