This reverts commit 2f87db990f.
PR #34359 was merged by mistake. On the bench, with an ESC on
YJUAV_A6SE_H743 output 1, the hold presents a continuous high (full
throttle to a PWM ESC) for about 10.5s after every reset, and for as
long as safety is engaged when output 1 is a motor outside
BRD_SAFETY_MASK, which is Copter's default. The ESC started to enter
throttle calibration. Back the change out until the hold can be
chosen per output.
