Make mach/irqs.h optional for SPARSE_IRQ. With this change mach/irqs.h can be removed by converting platforms over to sparse irq. Platforms either need to set nr_irqs in their machine desc or all irqchips used by a platform need to allocate their irq_descs. There cannot be a mixture. Once this is done, the platforms can select SPARSE_IRQ. shmobile does the latter, and mmp and pxa do the former. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
