Log Message:
Several changes to eliminate bogus controllers and sockets from being found:

PCIC_VENDOR_NONE: New.
PCIC_VENDOR_CIRRUS_*: Collapse the 2 chips into one vendor ID.

pcic_ident_ok(): Check the ID revision field -- if it's 0, punt.

pcic_vendor(): Check the ID revision field -- if it's 0, or the ID register
is all-1s, assume there is no chip present.  (Previously this would return
"Unknown controller" -- which, AFAICT, *never* resulted in a working device.)
Do the Cirrus check only after verifying that we got the Intel ID.

pcic_attach(): Use a priori knowledge of the Cirrus chips to determine the
number of sockets rather than trying (unsuccessfully) to probe.  Also, just
blast all of PCIC_INTR -- we do this in pcic_deactivate_card() anyway.
