Revert "drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume"

Browse source

This reverts commit b63a553e8f.

regcache_sync will try to reload the configuration in regcache to
hardware, but the registers of 4 Cluster windows and Esmart1/2/3 on
the upcoming rk3588 can not be set successfully before internal PD
power on.

Also it's better to keep the hardware register as it is before we really
enable it.

So let's revert this version, and keep the first version:
commit afa965a45e ("drm/rockchip: vop2: fix suspend/resume")
