LiPPERT FrontRunner-AF [2/2]: actually implement mainboard support

Step 2: change the Persimmon code to adapt it to the new board's hardware.

The FrontRunner-AF is a PC/104+ form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
  - DDR3 SO-DIMM socket (1.5 or 1.35V)
  - VGA and LVDS (via Analogix ANX3110)
- AMD A55E (Hudson-E1) southbridge
  - 6x USB 2.0
  - 1x SATA, 1x CFast socket
  - HD Audio (via Realtek ALC886)
  - PCI and ISA (via ITE IT8888)
  - NEC uPD78F0532 microcontroller on I2C ("SEMA")
- Intel I210 GbE (on APU PCIe x1)
- SMSC SCH3112 SIO
  - PS/2
  - 2x RS232/485
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)
