[PATCH 4/5] ARM: OMAP4: PM: Adapt the existing OMAP2/3 and common Power Domain Frameworks.

[Abhijit.Pagare at india.ti.com]

From: Abhijit Pagare <abhijitpagare at ti.com>

Taking care of the platform specific and common power domains with proper checks.
Also refining some Macros according to the latest OMAP4 requirements.
