Add support for the ASRock E350M1, an AMD family 14h Fusion board.
A video option rom must be added for UMA graphics support. It can
be extracted from the supplied UEFI BIOS.

ASRock E350M1 support is based on the AMD persimmon project. The
major differences are SIO model and DIMM SDP addressing. With this
coreboot and seabios, the board can boot DOS from a SATA drive and
can boot WinPE from a USB flash drive. I was unable to get
Windows setup to run.

The board has a socketed SPI flash BIOS chip and a serial port
header. The SIO is Nuvoton NCT5572D. Using coreboot's existing
Winbond w83627hf is a good enough match to get the serial port
and keyboard working.
