[RFC][PATCH 13/14] Convert sh to read/update_persistent_clock

[john stultz <johnstul@us.ibm.com>]

This patch converts the sh 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.
