540dfebf15 Rather than using individual HP300 model names, map those model names to 
properties such as "M68040" and "M68K_MMU_MOTOROLA", used to conditionally
compile code.  This is more in-line with now the other m68k ports do it,
and makes it much easier to find "common ground" among them.

In locore.s, use the MMU-type constants defined my <machine/cpu.h> rather
than "expanded" values.

Because HP300-model names are mapped to CPU/MMU combinations in
<machine/cpu.h>, no change to kernel configuration will be necessary.

9c784e07c1 Fix the integer overflow problem in pmap_init() when the user PT map is 
allocated, as noticed by Chuck Cranor.  In addition to re-arranging
the assignment as suggested by Niklas Hallqvist, check to see if maxproc
is higher than the number of available user PTs.  If it is, lower maxproc
to that value, the rationale being that it's much more desirable to have
fork() return EAGAIN than to have your system wedge.

XXX note that root can still raise maxproc with sysctl(2) later.  It's
probably worth having further discussion about this issue, but until
everyone has time to think about it, this seems like an acceptable solution
for the time being.

deb00c27b3 Use a "match/attach" rather than "init" scheme for probing devices. 
This is a step towards getting the drivers ready for new config.

Clean up namespace, remove several instances of global arrays.  Instead,
use a softc to carry state around.  Where possible, pass a pointer to
the softc rather than a unit number.

Pointers to hardware and software constructs are now stored per port
in each instance of the softc (one softc per board) rather than indexed
by minor number.
