When NFC is not enabled, IRQ will be disabled and
then if we do suspend/resume wake up functionality
won't be enabled at suspend but we try to disable
the same at resume and cause irq warning.
Fix warning trace in below cases :
1) NFC enabled in makefile, but manually turned off in
settings menu (NFC driver is enabled and hw is present).
2) NFC is not enabled in makefile
(NFC driver is enabled and hw is present).
