Replace it by a variable, which is initialized in amiga_init.c.
This will make the kernel actually work even if we have lots of Zorro-III
(or DraCo direct bus) i/o space.
the hp300 port.
- Interrupts 3-6 use this immediately. Interrupt 7 is a special case,
and the VIA interrupts (1 and 2) will be addressed when that code is
rototilled.
- Modify the zs front end to register with the appropriate interrupt
controller: through the PSC on the AV Quadras, and direct to
interrupt 4 on the rest. Arrange to have the appropriate zsc_softc
supplied to us at interrupt time.
- Modify the direct ADB driver (and its PowerManager cousin) to call
intr_dispatch(), rather than zshard(). XXX This is a kludge, but at
least limits the brokenness to the ADB drivers, now.
As a side effect, this should fix PR 5590. Thanks to Bill Studenmund for
correctly determining the cause of the problem reported there.

resolves a great many issues, including Performa 58x interrupt handling
and offset displays on some models.
Programs that depend on the old (pre-NetBSD 1.1) grf interface may break.
That's actually a separate issue uncovered by this code, not caused by it.
