Log:
flashrom: Winbond W39V040C and MSI K8T Neo2-F

W39V040C does standard JEDEC commands except chip erase so add a small driver.
probe_w39v040c() prints the block lock pin status when a chip is found.

The Neo2 board enable matches on 8237-internal IDE and onboard NIC PCI IDs.

Many thanks to Daniel McLellan for testing all of this on hardware!
Build tested by Uwe.
