MLK-17589: gpu/imx: Fix DCSS+DSI suspend/resume

Since the DCSS is not fully powered off when a suspend/blank occurs, the
next time we resume/unblank, the DCSS->DSI pipeline cannot be fully
re-initialized. In order to fix this issue, we should also not
completely power off the DSI too. Just configure it to stop
transmitting, by powering off the PHY.
