rtc: rzn1: clear interrupts on remove

Browse Source 
It is good practice to clear running interrupts before removing the
driver. This is not really a bugfix because on current systems RuntimePM
will disable the module clock, so interrupts won't be initiated. The
dependency on that behaviour is subtle, though. Better be self-contained
and clean up when removing.
