irqchip/apple-aic: Correctly map the vgic maintenance interrupt
We currently allocate the vgic maintenance interrupt by calling into
the low-level irqdomain code. Not only this is unnecessary, but this
is also pretty wrong: we end-up skipping a bunch of irqdesc state
setup
A simple "cat /proc/interrupt" shows how wrong we are, as the
interrupt appears as "Edge" instead of "Level".
Instead, just call the standard irq_create_fwspec_mapping(), which
is the right tool for the job. Duh.
