Fix all of the remaining 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.
