irqchip: Return -EPERM for reserved IRQs

The irqdomain core will report a log message for any attempted map call that fails unless the error code is -EPERM. This patch changes the Versatile irq controller drivers to use -EPERM because it is normal for a subset of the IRQ inputs to be marked as reserved on the various Versatile platforms.
