Use RUNTIME_PM_OPS() instead of the old SET_SYSTEM_SLEEP_PM_OPS().
This means we don't need __maybe_unused on the functions.

phy' is not implemented. Since the
DSI kernel clock is based on the internal DSI pll. The common clock
driver can not directly expose this 'ck_dsi_phy' clock because it does
not contain any common registers with the DSI. Thus it needs to be done
directly within the DSI phy driver.
