Cr50 should not automatically touch the EC reset when enabling the USB-EC SPI bridge. Otherwise, this could interefere with ECs that might have internal SPI flash and need to have their resets deasserted in order to access the internal SPI flash. This commits simply removes the assertion of EC reset when enabling the USB-EC SPI bridge. The user or external scripts should control the resets as necessary using servo or the cr50 console. BUG=b:71548795,b:71557464 BRANCH=None TEST=Flash meowth cr50. Verify that I can flash the EC using a servo_v4. TEST=Repeat above test with a servo_micro. TEST=Repeat above test with a SuzyQable.
