avr32: Convert avr32 to use read/update_persistent_clock
avr32: Convert avr32 to use read/update_persistent_clock

This patch converts the avr32 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.
