drm/i915/lobf: Disintegrate alpm_disable from psr_disable
Currently clearing of alpm registers is done through psr_disable()
which is always not correct, without psr also alpm can exist. So
dis-integrate alpm_disable() from psr_disable().
v1: Initial version.
v2:
- Remove h/w register read from alpm_disable(). [Jani]
