From: Peng Fan <peng.fan@xxxxxxx>
Without remove hook to clear wake irq, there will be kernel dump when
doing module test.
"bbnsm_rtc 44440000.bbnsm:rtc: wake irq already initialized"
Add remove hook to clear wake irq and set wakeup to false.
Fixes: eb7b85853c38 ("rtc: bbnsm: Add the bbnsm rtc support")
