st-touch: update script to new EC-based firmware
We are transiting from the old firmware to new EC-based firmware. The
new script checks if the trackpad is running old firmware, then flash
new EC firmware if it is the case. For trackpad that is already running
EC, we invoke flashrom to perform regular firmware update.
BUG=b:37187312,b:37584134
TEST=1) flash TP to old firmware, reboot the device and after an extra
reboot the TP is running EC firmware.
2) Place a new version of EC firmware onto the the device. Reboot
and the firmware should be updated to the latest version.
3) Like 2) but with RO WP enabled, after reboot EC_RW should be
updated to the latest version.
