Subject: [PATCH] irqdomain: Remove temporary MIPS workaround code

The MIPS interrupt controllers are all registering their own irq_domains
now. Drop the MIPS specific code because it is no longer needed.

Ralf, this should be okay to pull out now. I'll be submitting it for
v3.11 unless someone yells. Even if so, all the irqdomain infrastructure
is in place to make it trivial to add an irqdomain where missing.
