[PATCH v4 3/4] mach-snapdragon: fixup power-domains

RPMH power domain properties were initially removed from the
device tree due to the absence of driver support. Since RPMH
power domain driver is added now, the fixups are removed.

v4:
- Reverted the inclusion of qcom-rpmpd.h header in pervious versions.

v3:
- Removed OF_LIVE_SA8775P config, since there is no SA8775P specific fixups are done

v2:
- Removed the power domain fixups, since the power domains are handled in qcom-rpmhpd driver
