[PATCH] PCI: add proper MCFG table parsing to ACPI core.

[PATCH] PCI: add proper MCFG table parsing to ACPI core.

This patch is the first step in properly handling the MCFG PCI table.
It defines the structures properly, and saves off the table so that the
pci mmconfig code can access it.  It moves the parsing of the table a
little later in the boot process, but still before the information is
needed.
