drm/panthor: Fix undefined panthor_device_suspend/resume symbol issue
panthor_device_resume/suspend() are only compiled when CONFIG_PM is
enabled but panthro_drv.c doesn't use the pm_ptr() macro to conditionally
discard resume/suspend assignments, which causes undefined symbol
errors at link time when !PM.
We could fix that by using pm_ptr(), but supporting the !PM case makes
little sense (the whole point of these embedded GPUs is to be low power,
so proper PM is a basic requirement in that case). So let's just enforce
the presence of CONFIG_PM with a Kconfig dependency instead.
If someone needs to relax this dependency, it can be done in a follow-up.
