flasrom/flashprog could fail internal flashing.

A simple protection against this would be to
1- backup the current rom in memory
2- do whatever we currently do in flash.sh || flash backup rom in case of error

Be safer against possible user errors with chip specific SPI WP support landing iteratively under flashrom/flashprog and user interest into WP.

flash.sh: backup rom first, revert to backup if flashing fails for whatever reasons tlaurion/heads
