Reflect ardupilot PR 33229, which moves DDFP (and DDVP) tail-rotor motor control into the RSC controller: - DDFP tails now require SERVOx_FUNCTION "32" (HeliTailRSC) instead of "36" (Motor4). - Adds the H_TAIL_RAMP_TIME parameter, giving DDFP/DDVP tails an independent ramp-up time instead of DDFP having none and DDVP using the main rotor's H_RSC_RAMP_TIME. - Documents the new pre-arm check requiring H_TAIL_RAMP_TIME to be less than the main rotor's H_RSC_RUNUP_TIME.
