Tested on ASUS A8NE-FM with "SST SST49LF004A/B" (512 KB, FWH) and on a
Dr. Kaiser PCI card with a "Macronix MX29F001B" (128 KB, Parallel).
Tested all operations including erase/write multiple times for good measure.

Didn't check whether any new chips were added since this patch which
would also need their W bit removed. Feel free to merge that into the

No longer needed? Not used currently anywhere, it seems.
