irqchip/crossbar: Restore set_wake functionality
The TI crossbar irqchip doesn't provides any facility to configure the
wakeup sources, but the conversion to hierarchical irqdomains set the
irq_set_wake callback to irq_chip_set_wake_parent. The parent chip
(OMAP wakeupgen) has no irq_set_wake function either so the call will
fail with -ENOSYS. As a result the irq_set_wake() call in the resume
path will trigger an 'Unbalanced wake disable' warning.
Before the conversion the GIC irqchip was the top level irqchip and
correctly flagged with IRQCHIP_SKIP_SET_WAKE.
Restore the correct behaviour by removing the irq_set_type callback
from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which
lets the irq_set_irq_wake() call from the driver succeed.
