Michał Żygowski c7f0697867 coreboot_tables: Add new CBMEM ID to hold the PCI RB aperture info 
On AMD server systems there are multiple PCI root bridges. The root
bridge scanning in UEFI Payload is not sufficient to detect the
memory and I/O apertures properly. For example on Turin system, the
I/O aperture on the first root bridge containing the FCH may not
have any I/O resources detected on the PCI devices. This results in
the I/O decoding to be disabled on the root bridge, effectively
breaking the I/O based serial ports, e.g. on Super I/Os and BMCs.

Add new CBMEM ID to report the PCI root bridge aperture information
to the payload. The intention is to use the Universal Payload PCI Root
Bridges Info HOB that is already supported in the UEFI Payload. The HOB
will take priority over the root bridge scanning and properly report
the apertures of the PCI root bridges on AMD system.
