SpeedybeeF405V3 target has unreachable S9 servo output

[artempolikarpov]

Summary:
SpeedybeeF405V3 FC has S9 servo output pin.

If number of added servo is 5, there is PWN INIT ERROR on OSD and arming is disabled.

Steps to reproduce:

1. Add 5 servos on Mixer tab and Save
2. Go to CLI tab and type STATUS

Actual result:
Arming is disabled
PWM output init error: Not enough servo outputs/timers - message in CLI tab is displayed

You can try this file. I don't know for sure if it will work, so please let us know the results of your test.

Also, this issue should actually be in the INAV repo rather than INAV Configurator, so I have moved it.
