For some types of tuners (Philips FMD1216ME(X) MK3 currently) we know that
letting TDA9887 output port 1 remain high (inactive) will switch FM radio
to mono mode.
Let's make use of this functionality - nothing changes for the default
stereo radio mode.

Tested on a Medion 95700 board which has a FMD1216ME tuner.
