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.
