Log Message:
Add support for a single statically-allocated MCPCIA configuration structure,
which holds state of the MCPCIA to which the console is attached.

- All MCPCIA info is now stored in the mcpcia_config structure; the
mcpcia_softc only contains a struct device and a pointer to one of these.
- If attaching the console MCPCIA, use the static configuration, else allocate
the substructure.
- Rename mcpcia_init() to mcpcia_init0(), and make it take a "mallocsafe"
argument.
- Implement a new mcpcia_init(), which looks for the MCPCIA which has the
EISA bridge attached.  Initialize this MCPCIA as the console MCPCIA (the
console on the Rawhide is only allowed on this MCPCIA; firmware rule).
- Eliminate the kludgy linked listed of mcpcia_softcs.  Just use mcpcia_cd
to find all configured instances.

Separate bug fix: Actually clear the MCPCIA error mask after probing for
PCI (and ISA) devices, don't just clear it twice in mcpcia_init0().

Some other slight cleanup.
