From: Vaibhav Hiremath <hvaibhav@ti.com>
As far as PRM/CM/PRCM modules are concerned, AM33XX device is
different than OMAP3 and OMAP4 architectures; so we need to handle it
separately. This patch adds support for the PRM APIs required for
AM33XX device.

[paul@pwsan.com: separated the PRM parts of "ARM: OMAP3+: am33xx: Add
powerdomain & PRM support" into this patch; fixed Makefile prm33xx.o
location; cleaned up some checkpatch violations; updated for 3.5]

From: Vaibhav Hiremath <hvaibhav@ti.com>
As far as PRM/CM/PRCM modules are concerned, AM33XX device is
different than OMAP3 and OMAP4 architectures; so similar to
PRM implementation, handle AM33XX CM separately.
This patch introduces AM33XX CM module low-level api's, used and
required by omap clockdomain and hwmod framework.
Please note that cm-regbits-33xx.h (register bit field offset)
and cm33xx.h (register addr offset) files are mostly auto generated.

Add offset & mask fields to struct powerdomain
In case of AM33xx family of devices, there is no consistency between
PWRSTCTRL & PWRSTST register offsers in PRM space, for example -
PRM_XXX PWRSTCTRL PWRSTST
=======================================
PRM_PER_MOD: 0x0C, 0x08
PRM_WKUP_MOD: 0x04, 0x08
PRM_MPU_MOD: 0x00, 0x04
PRM_DEVICE_MOD: NA, NA
And also, there is no consistency between bit-offsets inside
PWRSTCTRL & PWRSTST register, for example -
PRM_XXX LOGICRET MEMON MEMRET
=======================================
GFX_PWRCTRL: 2, 17, 6
PER_PWRCTRL: 3, 25, 29
MPU_PWRCTRL: 2, 18, 22
WKUP_PWRCTRL: 3, NA, NA
This means, we need to maintain and pass on all this information
in powerdomain handle; so adding fields for,
- PWRSTCTRL/ST register offset
- Logic retention state mask
- mem_on/ret/pwrst/retst mask
Currently, this fields is only applicable and used for AM33XX devices.

From: Vaibhav Hiremath <hvaibhav@ti.com>
AM33XX PRCM module consist of, various clockdomains, in all
total we have 18 clockdomains available, with following
controlling options,
- SW Sleep: sw forced sleep transition
- SW Wakeup: sw forced wakeup transition
This patch adds all available clockdomain data, respective
clockdomain operations for AM33XX family of device, and also
integrates it into existing OMAP framework.
