[PATCH 04/11] ARM: zImage: fix comments for cache_on, cache_off and cache_clean_flush

[Uwe Kleine-König]

This adds missing registers to the list of corrupted registers and
removes a wrong comment about r9 on entry

While at it the formatting of the comment to cache_off is changed to
resemble the other two.
