add isa_intr_establish_xname() to MD isa headers so that it can be used
by MI drivers

branches: 1.7.22; 1.7.40; 1.7.44;
(Re-)define isa_detach_hook(), and define isa_dmadestroy(). Update
some isa_chipset_tag_t->ic_detach_hook() definitions.

Remove clause 3 and 4 from TNF licenses

branches: 1.5.16; 1.5.18; 1.5.20;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

A few ISA sound drivers like to share dma channels, and hence deferred
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.

To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.

All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.

New port: NetBSD/mvmeppc

Based mostly on NetBSD/prep at this time since the earlier mvme160x
boards are pretty much PReP compliant. Later boards in the range
diverge somewhat from the reference platform, hence the separate port.

Still needs *lots* of bashing into shape, but at this time it will
boot to multi-user over ethernet on an MVME1603-051.
