OMAP3: Fix typo and cp_delay

Fix typo and cp_delay.

Note that most of ARM code uses for-loop as cp_delay() implementation. Scott Wood made some tests and volatile prevents gcc from optimizing loop away, so this implemention should be fine. For OMAP some nops are sufficent, though.

Changes in v2:

- Correct patch header style.

v2 of this patch makes previous version v1 obsolete.
