futility: Prefer debug header servo over CCD when both are available.
BRANCH=none
BUG=b:270287312
TEST=With atlas DUT + servo_v4p1 + cr50_ccd + servo_micro:
$ dut-control -o servo_type # servo_v4p1_with_servo_micro_and_ccd_cr50
$ dut-control cpu_fw_spi # unknown value but control does exist
$ dut-control ccd_cpu_fw_spi # error from control not existing
$ futility read --servo -v ap-fw.bin # succeeds
With atlas DUT + servo_micro:
$ dut-control -o servo_type # servo_micro
$ dut-control cpu_fw_spi # unknown value but control does exist
$ dut-control ccd_cpu_fw_spi # error from control not existing
$ futility read --servo -v ap-fw.bin # succeeds
With atlas DUT + servo_v4p1 + cr50_ccd:
$ dut-control -o servo_type # servo_v4p1_with_ccd_cr50
$ dut-control ccd_cpu_fw_spi # off
$ futility read --servo -v ap-fw.bin # succeeds
