PATCH 1/2 ASoC: wm8991: Fix wrong bit setting for WM8991_POWER_MANAGEMENT_2

If (fakepower & ((1 << WM8991_INMIXR_PWR_BIT)|(1 << WM8991_AINRMUX_PWR_BIT)))) is false, we should clear WM8991_AINR_ENA bits instead of WM8991_AINL_ENA.

PATCH 2/2 ASoC: wm8991: Use snd_soc_update_bits for read-modify-write

Use snd_soc_update_bits for read-modify-write register access instead of open-coding it using snd_soc_read and snd_soc_write
