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.

Defer arc_init_wired_map() call after MD ipl_sr_bits[] is initilized

arc_init_wired_map() refers ipl_sr_bits[] via

Use C99 initializers.

Fix page size values passed to arc_wired_enter_page() for NEC-R96 and Tyne.
Detected by gxemul. (Wow, gxemul is also trying to emulate these machines!)

Adapt arc port to the new MI mips3 wired map functions.
Tested on NEC-RD94 with several PCI and jazzio devices.

- remove __P()
- use ANSI function decls
- u_intNN_t -> uintNN_t
- some KNF

__KERNEL_RCSID()

Add generic software interrupt support with mips/softintr.c.

Add c_nec_eisa_cons_init() for NEC-J96A and NEC-R96 which have
Cirrus Logic GD5428 ISA VGA console to initialize its registers properly
for generic vga(4) driver(s).

- Add definitions RD_94_[PVS]_EISA_{IO,MEM} in rd94.h.
- J96A (Express5800/240 R4400 EISA) requires different method to access
todclock from other NEC machines (it's similar with magnum),
so handle it in p_nec_j96a.c.

Now my NEC Express5800/240 works. (and now I can test 53c700 SCSI.)

fix duplicate wired TLB allocation, this is now done in {vga,pccons}_jazzio.c.
