Modified Files:
        src/sys/arch/x68k/conf: files.x68k std.x68k
        src/sys/arch/x68k/include: pmap.h pte.h vmparam.h
        src/sys/arch/x68k/x68k: locore.s machdep.c pmap_bootstrap.c

Log Message:
Make x68k port the new m68k pmap ready:

- Add new pmap files to config(5) file definitions
- Add commented out options __HAVE_NEW_PMAP_68K in conf/std.x68k
- Adjust <machine/pmap.h> and <machine/pte.h> for new pmap
  initialization ops etc.
- Update <machine/vmparam.h> for the new pmap specific address layout
- Tweak initializations in locore.s and pmap_bootstrap.c:
 - Save "boothowto" and "bootdev" registers earlier so that
   %d7 and %d6 can be used safely as other m68k ports
 - Rename pmap_bootstrap() -> pmap_bootstrap1()
 - Move initialization of "avail_start" and "avail_end" to x68k_init()
 - Allocate intio space using the pmap_bootmap structure and variables
   that represent I/O space region ("intiobase" and "intiolimit") in
   x68k_init() in __HAVE_NEW_PMAP_68K case

The new pmap kernel reaches single-user on (real) X68030.
On nono emulating X68030 init(8) gets Bus error as other ports.
