It is not required to use hard-coded offsets any more in context save and
restore functions and instead use the generic offsets which have been correctly
initialized during device registration.

Not related to this patch but saving the status register just useless.
You should rather save/restore 'wkup_set' register.
Can you please fix this in relevant patch. O.w this patch looks ok to
