ASoC: wm8994: Skip setting of the WM8994_MICBIAS register for WM1811

The WM8994_MICBIAS register is not available in the WM1811 CODEC so skip
initialization of that register for that device.
This suppresses an error during boot:
"wm8994-codec: ASoC: error at snd_soc_component_update_bits on wm8994-codec"
