Add support for Winbond W39F010/W39L010/W39L020

Browse Source 
W39F010 is a 128kB parallel 5V flash chip, 16k bootblocks.
W39L010 is a 128kB parallel 3.3V flash chip, 8k bootblocks.
W39L020 is a 256kB parallel 3.3V flash chip, 64k/16k bootblocks.

The W39F010 code was tested with a satasii programmer. The first write
attempt after an erase returned with verify failure, but the second
write attempt was succesful:

Corresponding to flashrom svn r1620.
