The bank power state bitfields in the powerdomain data are
encoded incorrectly.  These fields are intended to be bitfields,
representing a set of power states that the memory banks support.
However, when only one power state was supported by a given bank,
the field was incorrectly set to the bit shift -- not the mask.
While here, update some file copyrights.

The OMAP4 autogeneration scripts have been updated accordingly.

On OMAP4, there is an issue when L3INIT transitions to OFF mode without
device OFF. The SAR restore mechanism will not get triggered without
wakeup from device OFF and hence the USB host and USB TLL context
will not be restored.

Hardware team recommended to remove the OFF state support for L3INIT_PD
since there is no power impact. It will be removed on next OMAP revision
(OMAP4440 and beyond).

Hence this patch removed the OFF state from L3INIT_PD. The deepest
state supported on L3INIT_PD is OSWR just like CORE_PD and PER_PD

The l4per power domain in ES2.0 does support only RET and ON states.
The previous ES1.0 HW database was wrong and thus fixed on ES2.
Change the pwrsts field to reflect that.

The OMAP powerdomain code and data is all OMAP2+-specific.  This seems
unlikely to change any time soon.  Move plat-omap/include/plat/powerdomain.h
to mach-omap2/powerdomain.h.  The primary point of doing this is to remove
the temptation for unrelated upper-layer code to access powerdomain code
and data directly.

As part of this process, remove the references to powerdomain data
from the GPIO "driver" and the OMAP PM no-op layer, both in plat-omap.
Change the DSPBridge code to point to the new location for the
powerdomain headers.  The DSPBridge code should not be including the
powerdomain headers; these should be removed.

OMAP4 powerdomain control registers are split between the PRM hardware
module and the PRCM_MPU local PRCM.  Add this PRCM partition
information to each OMAP4 powerdomain record, and convert the OMAP4
powerdomain function implementations to use the OMAP4 PRM instance
functions.

Also fixes a potential null pointer dereference of pwrdm->name.

The autogeneration scripts have been updated.

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.

Back in the OMAP2/3 PRCM interface days, the macros that referred to
the offsets of individual PRM/CM instances from the top of the PRM/CM
hardware modules were incorrectly suffixed with "_MOD".  (They should
have been suffixed with something like "_INST" or "_INSTANCE".)  These
days, now that we have better contact with the OMAP hardware people,
we know that this naming is wrong.  And in fact in OMAP4, there are
actual hardware module offsets inside the instances, so the incorrect
naming gets confusing very quickly for anyone who knows the hardware.

Fix this naming for OMAP4, before things get too far along, by
changing "_MOD" to "_INST" on the end of these macros.  So, for
example, OMAP4430_CM2_INSTR_MOD becomes OMAP4430_CM2_INSTR_INST.

This unfortunately creates quite a large diff, but it is a
straightforward rename.  This patch should not result in any
functional changes.

The autogeneration scripts have been updated accordingly.

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.

Static data should be declared in .c files, not .h files.  It should be
possible to #include .h files at any point without creating multiple
copies of the same data.

We converted the clock data to .c files some time ago.  This patch does
the same for the powerdomain data.
