ASoC: wcd: add IRQF_NO_SUSPEND flag

If headset is inserted during suspend process,
pm will try to dispatch all the pending interrupts
before going to complete suspend. IRQ driver
waits for resume to get called which can lead to
a deadlock. So while registering for insertion/removal
interrupts add IRQF_NO_SUSPEND flag to avoid race condition
which can lead to deadlock.
