[PATCH] i386/x86-64: Only do MCFG e820 check when type 1 works

Needs earlier patch to split type 1 probing from use.

This patch should fix the x86 macs where type 1 PCI config space access
doesn't work, but MCFG does. They also don't have a usable e820 table
so the e820 sanity check failed.

Instead assume now that if type 1 doesn't work then MCFG must work
and don't do the e820 check.
