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

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

The Toucan-AF is a COM Express Compact Type 6 form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
  - 1-4 GB DDR3 memory down
  - 1x VGA, 2x DisplayPort (1 switchable to LVDS)
- AMD A55E (Hudson-E1) southbridge
  - 8x USB 2.0
  - 4x SATA
  - HD Audio (with codec on baseboard)
  - NEC uPD78F0532 microcontroller on I2C ("SEMA")
- 7x PCIe2.0 x1 (1 on PEG)
- Intel I210 GbE (on APU PCIe x1, can be disabled for additional PCIe)
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)

The Toucan-AF has no SIO on board.  This patch includes basic support for a
Winbond W83627DHG (PS/2, 2x RS232), because the ADLINK ExpressBase-6 used
for evaluation happens to have one.  The code may have to be adapted to the
actual baseboard of the application.
