drm/panfrost: Add GPU_PM_RT support for RZ/G3E SoC
RZ/G3E SoC is embedded with Mali-G52 GPU system. The system hangs after
STR in the following condition:
STR -> Wakeup from STR -> Unload panfrost using 'modprobe -r panfrost'.
Fix this issue by asserting/deasserting the reset during suspend/resume.
Rename the variable allwinner_h616_data->default_pm_rt_data for data
reuse and make it as generic GPU PM runtime data.
