[PATCH] fix comment for ppc_md enable/disable irq hooks

[Johannes Berg]

When committing the patch "Implement arch disable/enable irq hooks" in
commit 7ac5dde99eb9fefdb526973c600075b7c5703a86 you changed the code to
always call the generic decrementer/interrupt enabling/disabling but
forgot to update the comment, this fixes that.
