Board enable for Epox 8K5A2.

[Luc Verhaegen]

I didn't prepend this with [PATCH] yet, as i still need to verify this 
change on an epia-m with its original bios...

This patch adds support for the Epox 8k5a2 motherboard as owned by Kevin 
Sopp (CC). His lspci is attached for future reference. Kevin still needs 
to try this code too. His board is properly matched by pci subsystem 
ids, as there is one proper epox id in there, and the other id was 
copied from the device id (which is already better than leaving it 
blank).

This motherboard requires just the MEMW# on the winbond superio to be 
raised for it to work. 2 more boards with vt823x need this as well.

There are two other functions needed by other vt823x based boards;
* raising a vt823x gpio line (used 2x).
* enabling memory writes to always hit lpc on vt823x (used 2x).

By putting this code into separate functions, the vt823x board enables 
become very simple, with only the msi on still needing to poke a single 
pci bit on its own.

Kevin just confirmed on irc that this is working for his board. The 
epia-m test will sadly have to wait until tomorrow.

Eagle-eyed Uwe caught this here.
...
And now, as i was typing this email, he also spotted the fact that the 
function name is wrong...

Fixed locally, will send in with [PATCH] after testing on the epia-m 
(unless more things are found).

Thanks!

An updated version of the patch was already committed in r490, see
mails with subject "[PATCH] flashrom: Add EPOX 8k5a2".
