ifx: Add support for audio configuration of modem 

For the XMM6260 Infineon modem it is possible to use different audio
configuration depending on your platform. Currently the setup of
FULL_DUPLEX, BURSTMODE_48KHZ and BURSTMODE_96KHZ are supported. If
appropiate values for OFONO_IFX_MODEL and OFONO_IFX_AUDIO are set
in the udev rules file, then the audio configuration will be changed
when bringing up the modem.
