[flashrom] [PATCH] Add support for a bunch of 29GL parallel flash chips.

They use a new 3-Byte device ID probing function (although the first one
seems to always be a continuation indicator) at addresses 0x01, 0x0E, 0x0F.
Supported families include...
- EON EN29GL
- Gigadevice GD29GL (if they really exist)
- Macronix MX29GL (+MX68GL1G0F)
- Spansion 29GL (+S70GL02G)
- Winbond W29GL

Hello Gilbert,
I've tried to come up with a probing function that works on all 29GL chips.
Please apply the patch to r1796, recompile and post a verbose log,
e.g. by running './flashrom -p internal -o 29gl_probe.log and attaching
29gl_probe.log to the mail. Thanks!
I have very little experience with parallel flash chips so it might not
work at all. If it does detect the chip correctly, it will probably read
it correctly too, and maybe even erase it. I am not so sure about writing
though, so I would rather noth attempt writes or erases yet.
