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.
