Devices in the AUX block share a common interrupt line, with a register
indicating which devices have active IRQs. Expose this as a nested
interrupt controller to avoid IRQ sharing problems (easily observed if
UART1 and SPI1/2 are enabled simultaneously).

The interrupt functionality could arguably be forked off as a separate
irqchip driver, but the clock driver has already claimed the AUX_IRQ
register so some driver and DT surgery would still be required.
Eric Anholt thought that including it here is reasonable, but I'm
prepared to split it out if this is considered too hacky.
