x86, mrst: Don't blindly access extended config space
 
Do not blindly access extended configuration space unless we actively
know we're on a Moorestown platform.  The fixed-size BAR capability
lives in the extended configuration space, and thus is not applicable
if the configuration space isn't appropriately sized.

This fixes booting certain VMware configurations with CONFIG_MRST=y.

Moorestown will add a fake PCI-X 266 capability to advertise the
presence of extended configuration space.
