Done in preparation to move the CM driver to its own driver folder.
These drivers will not have access to functionality under mach-omap2 anymore.

Users of the CM funtionality should not access the CM registers directly
by themselves. Thus, added new CM driver APIs for the OMAP2 specific
functionalities which support the existing direct register accesses, and
changed the platform code to use these. This is done in preparation
for moving the CM code into its own individual driver.

There's no need to preserve the autodep handling code in
mach-omap2/cm2xxx.c, since no autodeps are defined for these chips.
Hopefully they'll never be needed, but if in some future case they are,
this code can be added back in.

Convert the OMAP clock code's _omap2_module_wait_ready() to use
SoC-independent CM functions that are provided by the CM code, rather
than using a deprecated function from mach-omap2/prcm.c.

This facilitates the future conversion of the CM code to a driver, and
also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed
by a subsequent patch.

Some modules have IDLEST registers that aren't in the CM module, such
as the AM3517 IDLEST bits. So we also need a fallback function for
these non-CM odd cases. Create a temporary one in mach-omap2/clock.c,
intended to exist until the SCM drivers are ready.

Convert the OMAP2xxx APLL code to use omap2_cm_wait_module_ready(),
and move the low-level CM register manipulation functions to
mach-omap2/cm2xxx.c. The objectives here are to remove the dependency
on the deprecated omap2_cm_wait_idlest() function in
mach-omap2/prcm.c, so that code can be removed later; and move
low-level register accesses to the CM IP block to the CM code, which
will soon be moved into drivers/.

Move the low-level SoC-specific clockdomain control functions into
cm*.c and prm*.c. For example, OMAP2xxx low-level clockdomain
functions go into cm2xxx.c. Then remove the unnecessary
clockdomain*xxx*.c files.

The objective is to centralize low-level CM and PRM register accesses
into the cm*.[ch] and prm*.[ch] files, and then to export an OMAP
SoC-independent API to higher-level OMAP power management code.

Move OMAP3xxx-specific CM functions & macros into cm3xxx.[ch] and
OMAP2xxx-specific macros into cm2xxx.[ch]. Move basic CM register
access functions into static inline functions in cm2xxx_3xxx.h,
leaving only OMAP2/3 hardreset functions in cm2xxx_3xxx.c.

As part of this, split the CM and hwmod code that waits for devices to
become ready into SoC-specific functions.

This is in preparation for the upcoming move of this code to drivers/.
