nicamd: Introduce new programmer driver for AMD NICs
On a PCnet32 FAST card with a nice PLCC32 socket, only 18 of the 20 ad-
dress lines were connected. It's not easy to detect this, but we'll do
our best: Check the ROM contents for repeating patterns, and allow the
user to override the guessed size. We use the ROM BAR here, though not
for the actual flash reading / writing. According to the datasheet the
ROM BAR interface always reads four bytes, and doesn't seem to support
writes.
Otherwise tested successfully with the first 256KiB of an SST39VF040.
