minute-ia: move IRQ definitions to common files
By moving the __irq_data extern declaration into link_defs.h, the
struct can be used in more than just interrupts.c.
In addition, this provides a common struct definiton for IRQ
definitions consisting of an IRQ number, the assigned routine, and a
handler function, which is a fairly common way to store IRQ
definitions.
BUG=none
BRANCH=none
TEST=arcada ISH functions as normal
