Subject: [PATCH] c67: irq: don't reimplement __handle_domain_irq()

c6x_do_IRQ() had a reimplementation of
__handle_domain_irq(), instead just call
that.

Patch wasn't even compile tested because I really don't
have c6x GCC around. If someone could test the patch before
applying, that would avoid regressions.
