[LinuxBIOS] [PATCH] Add ACPI MCFG table (resend)

[Rudolf Marek]

Hello,

This patch adds support for MCFG table, which allows OS to find the MMCONFIG for 
memory mapped PCIe config.

However this patch is not enough to enable it on Linux, Linux do not trust 
BIOSes too much, so a small patch to kernel to disable the check if this region 
is e820 reserved.

PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not using MMCONFIG.
