From: Peng Fan <peng.fan@xxxxxxx>
Without remove hook to clear wake irq, there will be kernel dump when
doing module test.
"bbnsm_pwrkey 44440000.bbnsm:pwrkey: wake irq already initialized"
Add remove hook to clear wake irq and set wakeup to false.
Fixes: 40e40fdfec3f ("Input: bbnsm_pwrkey - add bbnsm power key support")
