Cr50 holds the EC in reset when it wants to flash the EC or AP. This will trigger a pulse on the tpm reset signal. In early Cr50 versions when the tpm was reset we would reboot cr50, so we added some code to prevent cr50 from resetting itself when the update was going on. sys_rst_asserted would check if there was an update going on and ignore the signal if update in progress was true. At the end of the update the deferred function was used to reset Cr50 after the update was complete. None of this is needed anymore. We can just release the EC from reset at the end of the update. This change removes usb_spi_update_in_progress and the deferred update_finished. BUG=b:35571516 BRANCH=none TEST=flash the bob ec and ap using ccd.
