The dpu driver implements runtime_pm support for managing
dpu specific resources like - clocks, bus bandwidth etc.
Use pm_runtime_get/put_sync calls on dpu device.
The common clocks and power management for all child nodes
(mdp5/dpu, dsi, dp etc) is done by parent MDSS device/driver
via runtime_pm due to parent child relationship.
Changes in v3:
- none
Changes in v2:
- none
