move DEV_BSIZE, DEV_BSHIFT out of MD param.h, they are same on all ports

also move BLKDEV_IOSIZE, MAXPHYS, but allow override since some ports
have different value (powerpc uses NBPG for BLKDEV_IOSIZE, sun2/sun3
have lower MAXPHYS)

- include <mips/mips_param.h> after MACHINE is defined
- remove redundant comment

Remove clause 3 (UCB advertising clause) from the University of Utah
copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.

Extra verification by snj@.

Merge from matt-nb5-mips64
Merge mips-specific arch files.

Move MID_MACHINE to <mips/mips_param.h> and use local values so we don't
need to include exec_aout.h

branches: 1.7.60; 1.7.78;
Update algor clock handling. This includes using the common mc146818
support code, using the common MIPS 3 cp0 based interrupt code, adding
time counters, and using the generic TODR code.

Unfortunately, due to lack of hardware, I don't know for sure that any
of this works, though the same code in evbmips works. Commiting anyway,

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Purge CLSIZE, CLSIZELOG2 and MCLOFSET.
Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).

We are not a DECstation.

use _KERNEL_OPT

A port to the Algorithmics MIPS evaluation boards. We currently
support the P-5064, which has a QED RM5xxx CPU soldered on.

There is some skeletal support for the P-4032 (an older board, which
had an R4xxx CPU). There are some placeholders for the P-6032, which
is their newest board, but no real code yet (the P-6032 has a different
PCI controller, the Algorithmics BONITO).

There are still some (apprently softintr-related) problems with the
algor kernel, but it works well-enough to self-host.

Kudos to Allegro Networks for loaning me a P-5064 board on which to do
the port.
