ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER
This rewrites the IXP4xx to use MULTI_IRQ_HANDLER and create an irqdomain for the irqchip in the platform. We convert the timer to request the interrupt like any other driver in the process. We bump all IRQs to 16+offset to avoid using IRQ 0 and set NR_IRQS to 512 (the default for most systems). This conveniently fits with the first 16 IRQs being pre-allocated when using SPARSE_IRQ. This is a prerequisite for SPARSE_IRQ and DT boot. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
