MAINTAINERS: Remove myself from the general IRQ subsystem maintenance

It is pretty obvious that I haven't done much on the IRQ side
for a while, and it is unlikely that I'll have more bandwidth
for it any time soon. People keep sending me patches that
I end-up reviewing in a cursory manner, which isn't great for
anyone.

So in everyone's interest, I'm removing myself from the list
of maintainers and leave the irqchip and irqdomain subsystems
in Thomas' capable hands.
