ASoC: sgtl5000: Fix setting mic bias resistor


According to the datasheet:
CHIP_MIC_CTRL 0x002A

BITS[9:8] BIAS_RESISTOR
        0x0 = Powerd off
        0x1 = 2.0 kohm
        0x2 = 4.0 kohm
        0x3 = 8.0 kohm

To set mic bias resistor, we need to update bits[9:8] of
SGTL5000_CHIP_MIC_CTRL register.
