mb/bytedance: Add 2 SPR sockets server board bd_egs
Bytedance bd_egs is a dual socket MB with Intel Sapphire Rapids
Scalable Processor chipset.
It's utilising:
- 2 SPR sockets
- Max 32 DIMMs
- 33x CPU PCIe slots
- AST2600 for VGA and BMC remote management
Test:
The board boots to Linux 5.10 with all 192 cores available.
All PCIe devices and DIMMS are working.
# sudo dmesg --level alert,crit,err,warn
[ 46.636896] netlink: 'consul': attribute type 1 has an invalid length.
