Palmas extcon IRQs are nested threaded and wired to the Palmas
interrupt controller. So, this flag is not required for nested
IRQs anymore, since commit 3c646f2c6aa9 ("genirq: Don't suspend
nested_thread irqs over system suspend") was merged. However, the
fix in commit ae64e42cc2b3 ("extcon: palmas: Drop IRQF_EARLY_RESUME
flag") missed a stray flag causing the following crash on resume on
BeagleBoard-X15 platform:
