[ARM] OMAP2 PRCM: clean up CM_IDLEST bits

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.
