power_control: rework handling of DL RxQual measurements

This change makes BS power control loop:

  - take the lower RxQual threshold (L_RXQUAL_XX_P) into account, so
    the BS power is increased only if RxQual exceeds this threshold;

  - apply the configured increase step size instead of reducing the
    current attenuation by half.

MS power loop is not affected, it does not even handle RxQual yet.
