mvme68k: Specify proper constraints for bus_space_read region and multi ops.

Sync with next68k.

Remove cargo-culted '#if 0' code that was designed to produce a
compile-time error if any of the bus_space_*_8 functions was used,
but was documented that it produces a link-time error.

Provide PRIxBUSADDR, PRIxBUSSIZE, PRIuBUSSIZE, and PRIxBSH for all arches
to follow arm and (generic) mips.

Misc cleanup:
- KNF, ANSIfy, remove __P()
- use __func__ to print function names
- use __arraycount()
- include "ioconf.h" for struct cfdriver
- u_intNN_t -> uintNN_t
- wrap long lines
etc.

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

Simplify bus_space_{read,write}_N. Gcc3 emits better code than the old
compiler with straight C, rather than inline asm. (The latter was slightly
broken anyway with gcc3's more aggressive optimisation).

branches: 1.7.24;
Add register prefixes.

Replace the inline C versions of bus_space_{read,write}_N() with
inline assembler. This generates significantly more efficient code,
and trims ~1KB off the size of an mvme68k GENERIC kernel...

Merge 'scw_mvme68k_bus_space' branch with the trunk.
These changes add support for:

o The MI VMEbus framework on both MVME147 and MVME167.
o Enhancements to the existing MD bus_space(9) implementation.
o Most of the bus_dma(9) API.

branches: 1.4.2;
define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that
device accesses are idempotent (but should not be cached by the CPU)

branches: 1.3.2;
add BUS_SPACE_ALIGNED_POINTER() definitions for completeness

branches: 1.2.4;
Merge support for mvme167 into main tree.

file bus_space.h was initially added on branch scw-mvme167.
