Shared-Added RSSI fields to manualcontrol settings and command UAVO.
Flight-ManualControl module populate RSSI UAVO fields from PWM,PPM or ADC
Flight-UAVOMavlinkBridge send new RSSI value on mavlink stream
Flight-ManualControl Module-wrap ADC funcion call in #IFDEF
shared-manualcontrolsettings uavo-fix RssiMin/Max values
shared-manualcontrolsettings uavo-Added RssiPwmPeriod field
flight-modules-manualcontrol Handle new ManualcontrolSettings RssiPwmPeriod field

If the period is 0 use the value from the PWM driver directly.
If not 0 use the (measured positive pulse width) % (frame width)
formula.
This is a workaround to handle FrSky high frequency PWM RSSI.
