Add support for the Open Graphics Project development card, OGD1, as a
SPI flash programmer. The project is in the the process of designing
and making a complete, open source, graphics card.
More info at ​http://wiki.opengraphics.org.

The first development card is a PCI add in card containing a couple of
FPGAs and a couple of serial flash chips (amongst other things). The
FPGAs are called XP10 and S3 (their part numbers). The XP10 contains
its own flash and does not need to be programmed by flashrom - it
ensures that the device can enumerate on the PCI bus without needing
further configuration.

The larger FPGA is the S3. This is configured from a large SPI flash
(2 MBytes). The second SPI flash is used to store the VGA BIOS. It
is smaller (128 KBytes). This patch adds support for programming either
of the two SPI flash chips.

The programmer device takes one configuration option which selects which
of the two flash chips is accessed. This must be set to either "cprom"
or "bprom". (The project refers to the two chips as "cprom" / "bprom",
"s3" and "bios" are more readable alternatives).

Add support for SST SST25VF010 (REMS).
Mark SST SST25VF016B as tested for write.
