The cs4265 driver is missing a microphone preamp enable.
This patch enables/disables the microphone preamp when mic
selection is made using the kcontrol.

This looks good but I think you should also remove the existing
routes that put the mic straight into the ADC Mux.
{"ADC Mux", "MIC", "MICL"},
{"ADC Mux", "MIC", "MICR"},
