[PATCH 1/2] mfd: pm8921: Drop irq_set_lockdep_class() code

[Stephen Boyd]

This isn't necessary as we aren't setting the summary interrupt
to wake up the system in the irq_wake() callback.

[PATCH 2/2] mfd: pm8921: Use IRQCHIP_SKIP_SET_WAKE

[Stephen Boyd]

We don't need to implement a dummy irq_set_wake op if we just set
IRQCHIP_SKIP_SET_WAKE.
