Telemetry switch: fix stupid mistake
reverting previous fix. This doesn't solve all conditions.
I need to add a telemetry_switch conf or feature to solve enabling MSP over FRSKy with switch not activated when armed ( i.e. using bt serial for tuning sessions ), but it will break when not using telemetry switch.
Better to keep it like this for now.
Added a mcfg.telemetry_switch for CLI
If telemetry_switch=1 it change baudrate and protocol using aux channel, either it switch  when armed/disarmed.

This allows to keep MSP serial while armed for BT dongle if needed.

new althold PID

althold should work better now, the PID settings are preliminary. There
is definetly room for improvement.
For aquiring your own PID settings set ALT_P = 0 and tune the VEL pid
until the copter only drifts a little from its position when you
activate althold. Then set ALT_P to a value where it holds the position
stable
