Disable the plane if it's not visible. Otherwise mtk_ovl_layer_config()

When suspending the driver, anx7625_power_standby() will be called to
turn off reset-gpios and enable-gpios. However, power supplies are not
disabled. To save power, the driver can get the power supply regulators
and turn off them in anx7625_power_standby().

Currently in arm64, FDT is mapped to RO before it's passed to
early_init_dt_scan(). However, there might be some codes
(eg. commit "fdt: add support for rng-seed") that need to modify FDT
during init. Map FDT to RO after early fixups are done.

Introducing a chosen node, rng-seed, which is an entropy that can be

Adding "rng-seed" to dtb. It's fine to add this property if original
fdt doesn't contain it. Since original seed will be wiped after
read, so use a default size 128 bytes here.

Does nothing as default, arch can implement their function to map
fdt to RO/RW. This is convenient if arch map fdt to RO during init
but needs to write fdt in some special cases after that.

Basically does similar things like __fixmap_remap_fdt(). It's supposed
to be called after fixmap_remap_fdt() is called at least once, so region
checking can be skipped. Since it needs to know dt physical address, make
a copy of the value of __fdt_pointer.
