samus: add host commands for flashing zinger RW
This adds a new host commmand for sending RW updates to PD devices.
The host command has a variety of sub-commands for performing the
update, including: erase RW, reboot, write new hash, write flash.
To program zinger RW, you should send host commands in this order:
write new hash to all 0's
reboot (zinger boots into RO since RW hash doesn't match)
erase RW
write flash
write new hash to match contents of RW
reboot
This also adds an ectool command to write a new RW. Just pass it
the RW .flat or .bin file.
