Mark each interface clock with a corresponding CM_AUTOIDLE bit with
a clkops that has the allow_idle/deny_idle function pointers populated.
This allows the OMAP clock framework to enable and disable autoidle for
these clocks.

Reverse some of the effects of commit
84c0c39aec ("ARM: OMAP4: PM: Make OMAP3
Clock-domain framework compatible for OMAP4"). On OMAP2/3, the
CM_CLKSTCTRL register is at a constant offset from the powerdomain's
CM instance.
Also, remove some of the direct CM register access from the
clockdomain code, moving it to the OMAP2/3 CM code instead. The
intention here is to simplify the clockdomain code. (The long-term
goal is to move all direct CM register access across the OMAP core
code to the appropriate cm*.c file.)

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.

Add hwmod structures for I2C controllers on OMAP2420/2430.
NOTE: I2C module on OMAP2420 has 16bit registers and causes imprecise
aborts if 32bits are read/written to it. Use the HWMOD_16BIT_REG flag
to notify the hmwod framework of this hard requirement so that
__raw_writew/readw is used to read /write the mdoule registers.

Fix all of the remaining OMAP2 PRCM register shift/bitmask macros that
did not use the _SHIFT/_MASK suffixes to use them. This makes the use
of these macros consistent. It is intended to reduce error, as code
can be inspected visually by reviewers to ensure that bitshifts and
bitmasks are used in the appropriate places.

This patch fixes a few OMAP2xxx CM_IDLEST bits that were incorrectly
marked as being OMAP2xxx-wide, when they were actually 2420-specific.
Also, originally when the PRCM register macros were defined, bit shift
macros used a "_SHIFT" suffix, and mask macros used none. This became
a source of bugs and confusion, as the mask macros were mistakenly
used for shift values. Gradually, the mask macros have been updated,
piece by piece, to add a "_MASK" suffix on the end to clarify. This
patch applies this change to the CM_IDLEST_* register bits.
The patch also adds a few bits that were missing, mostly from the 3430ES1
to ES2 revisions.

This patch adds common register access for 24xx and 34xx power
and clock management in order to share code between 24xx and 34xx.
Only change USB platform init code to use new register access, other
access will be changed in later patches.
