Add a platform device for the r8a7791 IRQC hardware
driving IRQ pins IRQ0 to IRQ9. The Linux interrupt
number is statically assigned to allow board code
written in C to make use of static interrupt numbers.

Thanks, I have queued this up in the soc3 branch.
It should make it into v3.13 but if not I'll rename the branch
soc after rebasing it on v3.13-rcX which will then be targeted at v3.14.
