Doing a hard reboot after a usb spi transaction is overkill. This
changes the hard reboot to a EC reset so the AP, EC, and TPM will reset
without affecting ccd.
BUG=none
BRANCH=none
TEST=running 'sudo flashrom -p raiden_debug_spi:target=EC' doesn't
interfere with the cr50 console but resets the AP, EC, and TPM.
