Use m68k/m68k/bus_dma.c
- Add mainbus_attach_args with bus_space_tag_t and bus_dma_tag_t.
- Use passed-in tags for nubus scan.

Add a DIAGNOSTIC panic if (count-using) bus_space macros are called with
...
a count of zero. Some drivers do this accidentally and some bus_space
implementations will fail if count is passed as zero (they are set up in
a do-{}-while structure).

Make sure that bus_space read/write functions that take a count will not be
...
called if count is zero. The smc91cxx driver, for example, may try to call
bus_space_write_multi_2() with a count of 0.

Add byte-swap and stride options to bus_space. Allocate as normal, then
...
call mac68k_bus_space_handle_swapped() or mac68k_bus_space_handle_set_stride().
Stride is untested. Swapped code works for SMC ethernet.

device accesses are idempotent (but should not be cached by the CPU)

Add a macro to check for sufficient pointer alignment in bus.h context,
...
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)
