regmap: irq: initialize all irqs to wake disabled
The kerneldoc for irq_set_irq_wake() says:
Enable/disable power management wakeup mode, which is
disabled by default.
regmap_irq_set_wake() clears bits to enable wake for an interrupt,
and sets bits to disable wake. Hence, we should set all bits in
wake_buf initially, to mirror the expected disabled state.
