PM / devfreq: rk3399_dmc: Block PMU during transitions
See the previous patch ("soc: rockchip: power-domain: Manage resource
conflicts with firmware") for a thorough explanation of the conflicts.
While ARM Trusted Firmware may be modifying memory controller and
power-domain states, we need to block the kernel's power-domain driver.
If the power-domain driver is disabled, there is no resource conflict
and this becomes a no-op.
