Make Cros EC skip sysjump if code runs in RAM

Sysjump isn't necessary for the ECs which execute code in RAM.

This patch makes the flashrom utility query the cros EC whether it
runs code in RAM or not. If so, the flashrom utility will assume
it's safe to erase and write the blocks even if they're part of
the regions where the EC is currently executing the code.

BUG=b:77306460
TEST=Run flashrom -p ec -w /path/to/ec.bin on Fizz.
Verify EC doesn't sysjump.
