connected instead of the 'midrc' value.

Achieved by deleting unnecessary legacy ardino code.

Basically it was there because the Ardiuno PPMSUM timer resolution is
lower than the STM32 code we use.

With a Grapner GR-24 receiver using parallel PWM or PPM (12channel) the
values hardly fluctuate at all, slightly more noticable with parallel
PWM input.
