Subject: [PATCH 11/14] m68k: Convert m68k to use read/update_persistent_clock

This patch converts the m68k architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future.

I have not built or tested this patch, so help from arch maintainers would be appreciated.
