Bump the IRQ numbers from offset at 1 (right above NO_IRQ) to 32. This is the painful way to learn that if you're using SPARSE_IRQ and avoid to define .nr_irqs in your machine, the first 16 IRQs will be pre-allocated, and the IRQdomain code (as the VIC core code before it) will then assume that all IRQ descriptors are pre-allocated, and 16 of them are - by somebody else. So mapping the IRQs will fail in irq_create_mapping(). Moving the offset upward rids us of this problem.
