Disable writes on default for known bad programmers

If a programmer has untested or non-working write/erase code, but
probing/reading works, it makes sense to protect the user against
write/erase accidents. This feature will be used by the Nvidia MCP SPI
code, and it also might make sense for the gfxnvidia driver which has
non-working write/erase.
