Subject: [PATCH] ARM: irq migration: update GIC migration code

This cleans up after the conversion to irq_data.  Rename the function
to match the method, and remove the now useless lookup of the irq
descriptor which is never used.  Move the bitmask calculation out of
the irq_controller_lock region.
