media: platform: rzg2l-cru: rzg2l-csi2: Switch to RUNTIME_PM_OPS()

Replace the old SET_RUNTIME_PM_OPS() helpers with its modern alternative
RUNTIME_PM_OPS(). The usage of pm_ptr and RUNTIME_PM_OPS() allows the
compiler to see where it's used but still drop the dead code. After this
we can get rid of the unnecessary '__maybe_unused' annotations on PM
functions.
