i945: make PCIe link wait sensible
Waiting for (a & 4) == 3 to become true proves futile
unless you're searching for defective hardware or
neutrino impact.
While I'm not 100% sure that this is the actual intent
(no data-sheets at hand, and the public ones are unhelpful
as usual), it's the likely correct version and it's also
boot-tested on intel/d945gclf.
While at it, replace register number with the name found
in the public datasheet.
