Merge branches 'depends/irqdomain' and 'at91/base2+cleanup' into next/dt

These two branches are a dependency for the at91 device tree changes,
so we pull them in here. at91/base2+cleanup will get merged through
the arm-soc cleanup2 branch, while the irqdomain tree will be sent
by Grant before this one gets integrated.
