futility: updater: Support new servo control 'ccd_cpu_fw_spi'

Some newer devices need extra preparation steps even when using CCD via
servo, so a new 'ccd_cpu_fw_spi' is added to hdctools. The firmware
updater should use it in servo+ccd modes.

Also, the custom_rst is now moved to detect_servo so the --servo_noreset
option is removed.
