Markus Schneider-Pargmann b6f5f0c8f7 hwrng: mtk - Force runtime pm ops for sleep ops 
Currently mtk_rng_runtime_suspend/resume is called for both runtime pm
and system sleep operations.

This is wrong as these should only be runtime ops as the name already
suggests. Currently freezing the system will lead to a call to
mtk_rng_runtime_suspend even if the device currently isn't active. This
leads to a clock warning because it is disabled/unprepared although it
isn't enabled/prepared currently.

This patch fixes this by only setting the runtime pm ops and forces to
call the runtime pm ops from the system sleep ops as well if active but
not otherwise.

Fixes: 81d2b34508 ("hwrng: mtk - add runtime PM support")
