ASoC: wm9081: Don't write WM9081_BIAS_ENA bit to WM9081_VMID_CONTROL register
WM9081_BIAS_ENA is the bit[1] of WM9081_BIAS_CONTROL_1 register (05h). Current code incorrectly write it to WM9081_VMID_CONTROL(04h) register. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
