audio:sai:mqs: Patch mqs and sai driver to fix audio popping on NALLINO

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.

dts:arm:seco:nallino: Add always on to two hardwired regulators

The regulators are always logically disabled by the kernel, though they are hardwired on. The always on flag should change this and remove the messages.
