[SeaBIOS] [PATCH 2/2] pci/acpi: add mcfg table for mmconfig

/me was thinking about making the 32bit pci window dynamic on q35 too,
so the mmconfig base address wouldn't be fixed any more.  Didn't do it
in the end because the window is larger on q35 anyway (qemu wouldn't map
ram above 0xb0000000).  So, yes, we can just hard-code stuff.

cheers,
