e1000e: write protect ICHx NVM to prevent malicious write/erase
Set the hardware to ignore all write/erase cycles to the GbE region in
the ICHx NVM. This feature can be disabled by the WriteProtectNVM module
parameter (enabled by default) only after a hardware reset, but
the machine must be power cycled before trying to enable writes.
