OMAP4: PRCM: reorganize existing OMAP4 PRCM header files

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.
