This gets rid of need for some exported driver APIs, and simplifies the
initialization of the CM driver. Done in preparation to make CM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

There is no need to call this separately from io.c, rather this can be
done commonly under the CM driver. Also, this patch makes the API static,
as it is no longer used outside the driver file.

cminst44xx.h will be removed, thus move the public APIs to cm44xx.h header.

The CLKCTRL register was accessed using an absolute address.
The usage of hardcoded macros to calculate virtual address from physical
one should be avoided as much as possible.
The usage of a offset will allow future improvement like migration from
the current architecture code toward a module driver.
Update cm_xxx accessor, move definition to the proper header file and
update copyrights.

omap4_clkdm_clear_all_wkup_sleep_deps(); thanks to Kevin Hilman for finding
and helping fix this bug]

In preparation for adding OMAP4-specific PRCM accessor/mutator
functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific
files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been
moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was
OMAP2xxx/3xxx-specific.
This process also requires the #includes in each of these files to be
changed to reference the new file name. As part of doing so, add some
comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use
"sideways includes", to indicate that these users of the PRM/CM includes
should not be doing so.
Thanks to Felipe Contreras <felipe.contreras@gmail.com> for comments on this
patch.

Split the existing cm44xx.h file into cm1_44xx.h and cm2_44xx.h files
so they match their underlying OMAP hardware modules. Add clockdomain
offset information.
Add header files for the MPU local PRCM, prcm_mpu44xx.h, and for the
SCRM, scrm44xx.h. SCRM register offsets still need to be added; TI
should do this.
Move the "_MOD" macros out of the prcm-common.h header file, into the
header file of the hardware module that they belong to. For example,
OMAP4430_PRM_*_MOD macros have been moved into the prm44xx.h header.
Adjust #includes of all files that used the old PRCM header file names
to point to the new filenames.
The autogeneration scripts have been updated accordingly.

The cm44xx.h files only had absolute register address
defines for all CM registers.
This patch adds additional register offset defines for all the
registers, so they can be used with apis like cm_read_mod_*

The automatic HW restore from OFF mode is not functional at all in
OMAP4430 ES1.0.
Because of that, it will be extensively changed in the next Si revision,
and the compatibilty will not be maintained with ES1.0.
Remove the current XXX_RESTORE registers definition to avoid future
conflicts with the next Si revision.
