[PATCH 2/5] ARM: OMAP4: PM: OMAP4 Power Domain Porting Related Clean-up.

[PATCH 2/5] ARM: OMAP4: PM: OMAP4 Power Domain Porting Related Clean-up.

[Abhijit.Pagare]

From: Abhijit Pagare <abhijitpagare@ti.com>

Module offsets were same for OMAP2 and OMAP3 while they differ for OMAP4.
Hence we need different macros for identifying platform specific offsets.
