audio:mqs: Fix audio popping when using the MQS

The i.MX6 ULL has an audio block equipped, that can generate audio via a
standard GPIO. Since the MQS (Medium Quality Sound) is a very basic audio
interface, it doesn't provide any filtering of unwanted artifacts in the
audio stream. This leads to a popping noise when playing audio on the
Nallino. The patch changes the SAI to always generate a signal for the
MQS and transfers the control of the external amplifier to the MQS driver.
This helps in reducing the noticeable interference when playing audio.
