Differentiate Numonyx N25Q064 1.8V and 3.0V versions
This patch differentiates between the N25Q064 1.8V version and 3.0V
version which have different JEDEC IDs.
It extends the chip name to include more characters of the part
number. The first two of those characters indicate the process
technology (65nm) and feature set (hold pin etc.), neither of which
matter for flashrom at the moment. The third and fourth characters
specify voltage and block/sector size and uniformity, which are
important and hence included.
To abstract the irrelevant portions of the part number leading up to
the characters we care about, dots are used. This helps prevent
unwanted changes in chip name that can break fragile scripts and
confuse people. More about this schema here:

Corresponding to flashrom svn r1612.
