drm/panthor: Drop the dev_enter/exit() sections in _irq_suspend/resume()

There's no reason for _irq_suspend/resume() to be called after the
device has been unplugged, and keeping this dev_enter/exit()
section in _irq_suspend() is turns _irq_suspend() into a NOP
when called from the _unplug() functions, which we don't want.

v3:
- New patch
