gpio: crystalcove: use handle_nested_irq
The CrystalCove GPIO chip has can_sleep set so its demultiplexed irqs will have IRQ_NESTED_THREAD flag set, thus we should use the nested version handle_nested_irq in CrystalCove's irq handler instead of handle_generic_irq, or the following warning will be hit and the functionality is lost: [ 4089.639554] Hardware name: ASUSTeK COMPUTER INC.
