Gimbal manual control doesn't work

[eshcheglov]

Steps to Reproduce:

Follow the official instruction

1. Set MNT_MODE_OUT=AUX
2. Set MNT_MODE_IN=Auto
3. Configure Gimbal Servo using Actuators tab:

PWM:       200Hz
AUX 5:     "Gimbal Pitch"
Disarmed:  1000
Minimum:   1100
Maximum:   1900

4. Verify that gimbal servo is working using Actuator Testing
5. Set MNT_MAN_PITCH=AUX5
6. In Joystick -> Button Assigment tab set Gimball Up and Gimball Down to some buttons on connected USB joystick

Gimbal work automatically:

• It change position after arming
• It changing position relatively to frame position if MNT_DO_STAB is enabled. So I can assume that gimbal is actually working, but I can't manipulate it manually for some reason
