Jetway NF81-T56N-LF [2/2]: actually implement mainboard support.

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

The NF81-T56N-LF is a IPC form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) APU
  - 2x SO-DIMM sockets for DDR3 800-1066 SDRAM (Fixed at 1.5V)
  - VGA and LVDS (via Analogix ANX3110)
- AMD A55E (Hudson-E1) southbridge
  - 6x USB 2.0/1.1 ports
  - 5x SATA3 6Gb/s, 1x mSATA socket
  - 6-Channel HD Audio (via VIA VT1705)
  - PCI and ISA (via ITE IT8888)??
  - NEC uPD78F0532 microcontroller on I2C ("SEMA")??
- 2x RJ45 GbE (via Realtek RTL8111E x2)
- Fintek F71869AD Super I/O
  - PS/2 KB/MS port
  - RS232 header (via Unisonic UTC 75232 RS232 driver/receiver)
  - GPIO header
  - CIR header
- 1x MXIC MX25L1606E (SO8, soldered) 16 Mbit SPI flash (BIOS)

Note: MX25L1606E is 16Mbit, 8bits in a byte, so 2MB. Jetway *lies*
claiming the SPI flash is 16MB. They also use red pen over the chip
so you wont see this deceit.
