[PATCH-V3 0/3] ARM: OMAP4: Remove hardcoded reg-offs for PWRSTCTRL & PWRSTST

This patch series removes the existing hard-coded way of providing
offset to omap4_prminst_xxx API's and instead use offsets
provided in powerdomainsxxxx_data.
Also, hook up AM33XX device support to existing omap4 PRM code.

Background:
==========
PRM module in AM33XX is closer to OMAP4 PRM module, so it complete
sense to reuse all the code from existing OMAP4 implementation.
Having said that, there is a catch here with respect to AM33XX device,

The register offset in PRM module is not consistent
across (crazy IP integration), for example,

PRM_XXX         PWRSTCTRL PWRSTST RSTCTRL RSTST
===============================================
PRM_PER_MOD:    0x0C,     0x08,   0x00,   0x04
PRM_WKUP_MOD:   0x04,     0x08,   0x00,   0x0C
PRM_MPU_MOD:    0x00,     0x04,   0x08,   NA
PRM_DEVICE_MOD: NA,       NA,     0x00,   0x08

So in order to reuse the existing OMAP4 code, we have to add
seperate entry for register offsets, especially
PWRSTCTRL & PWRSTST.

NOTE: Boot tested on AM335x EVM and AM37xEVM

Changes from V2:
	- As per Kevin's comment, created separate prm_base table
	  for am33xx and added __init function for prminst to
	  initialize prm_base table during boot time.
	- Minor comment from Kevin, to add extra line in patch 1/3
Changes from V1:
 	- As per Kevin's comment, patch is split into logical
	  commits for ease of review.
  	- Added specific comment for cpu_is_xxx check order
	  change.

Kevin,

Any comments on this patch-series?

Thanks,
