Move the defines for the APCI1564_DI_IRQ_REG from the included source file
to the main driver source file.
For aesthetics, rename the bit defines so they have namespace associated
with the register define. Also, remove the unnecessary 'disable' define
and convert the 'enable' define to a bit-shift.
