memshare: Free the memory after XPU unlocking is done



Currently memshare driver is listening to notification
SUBSYS_AFTER_SHUTDOWN, which doesn't guarantee the unlocking
of XPU for the clients sitting on peripheral. This could lead
to a XPU violation. Move the notification to free up memory
during SUBSYS_BEFORE_POWERUP to ensure that the allocated memory
XPU has been removed.
