mb/msi/h81m-p33: Add new mainboard

This is a µATX mainboard with a LGA1150 socket and two DDR3 DIMM slots.

Working:
 - Both DIMM slots
 - Serial port to emit spam
 - Some USB ports
 - Integrated graphics (libgfxinit)
 - DVI
 - Realtek GbE
 - All PCIe ports
 - At least one SATA port
 - RAM initialization with MRC binary
 - Flashing with flashrom
 - S3 suspend/resume
 - VBT
 - SeaBIOS 1.14 to boot Arch Linux (kernel linux-5.10.15.arch1-1)

Broken:
 - Audio. It doesn't work on stock firmware either.
   I suspect the codec hardware on my board is dead.

Untested:
 - PS/2 mouse
 - EHCI debug
 - Front USB headers
 - Non-Linux OSes
 - TPM header
 - VGA
