x86_64: Move functions declarations to header file
Some interrupt entry points are currently defined in i8259.c They probably
belong in a header. Right now, their only user is init_IRQ, justifying
their declaration in-file. But when virtualization comes in, we may be
interested in using that functions in late initializations.
