mb/ibm: Add 4 SPR sockets server board IBM SBP1

The IBM SBP1 is an evaluation platform.

It's utilising:
- 4 SPR sockets, having 16 DIMMs each
- 240C/480T at maximum
- 32x CPU PCIe slots
- 2x M.2 PCH PCIe slots
- Dual 200Gbit/s NIC
- SPI TPM

It has an AST2600 BMC for remote management.

It doesn't have:
- External facing USB ports
- Video outputs
- Audio codec

Test:
  The board boots to Linux 5.15 with all 480 cores available.
  All PCIe devices are working and no errors in ACPI.
  All 64 memory DIMMS are working and M.2 devices can be used.
