Subject: [PATCH 10/46] ARM: pxa: pxa2xx-ac97-lib: use IRQ resource

The pxa2xx-ac97-lib code is the last driver to use mach/irqs.h
for PXA. Almost everything already passes the interrupt as
a resource, so use it from there.

The one exception is the mxm8x10 machine, which apparently has
a resource-less device. Replacing it with the correct one
enables the driver here as well.
