MLK-23116-11 gpu: imx: imx8_dprc: Support hard argument for dprc_disable()
As we would support some non-native prefetch engine pixel formats
soon later with some coming patches, hot-switch from native pixel
formats to non-native ones(on-the-fly PRG bypass) is inevitable.
Basically, dprc_disable() is called to do the switch. If a follow-up
modeset is done to enable the prefetch engine again, we see prefetch
engine fail-over issue. So, a reset is needed in dprc_disable()
in the need_modeset case. It appears that PRG reset is enough.
