[PATCH 7/9] media: rzg2l-cru: csi2: Add system sleep PM support

[Tommaso Merciai]

The rzg2l-csi2 driver has runtime PM callbacks but no system sleep
hooks,leaving the device in an undefined state across system
suspend/resume.

Wire up SYSTEM_SLEEP_PM_OPS with pm_runtime_force_suspend/resume to
reuse the existing runtime PM callbacks for system sleep.
