PCI: avoid early PCI mmconfig init if pci=noearly is given in cmdline

Early type 1 accesses can cause problems on some platforms, and
pci=noearly is supposed to prevent them from occurring.  However, early
mcfg probing code uses type 1 and  isn't protected by a check for
noearly.  This patch fixes that problem.
