[LinuxBIOS] PATCH: vt8237 support for flashrom.

[Uwe Hermann]

Hi,

here's a tiny patch to make flashrom work on an vt8237-based board.

I tried using both enable_flash_vt8231() and enable_flash_vt8235(),
and both work fine for the vt8237, it seems.
I tested probing, reading and writing achip. All of that worked with
a few 512K chips. However, some other 256K chips were not detected
properly, but that might be another issue...

Uwe.
