[PATCH v2 0/2] ASoC: qcom: common: Parse auxiliary devices from device tree

In some cases we need to probe additional audio components that do
not appear as part of the DAI links specified in the device tree.
Examples for this are auxiliary devices such as analog amplifiers
or codecs.

The ASoC core provides a way to probe these components by adding
them to snd_soc_card->aux_dev.

This patch set allows specifying them in the device tree through
a new "aux-devs" property.

v1: https://lore.kernel.org/linux-arm-msm/20200819091533.2334-1-stephan@gerhold.net/
Changes in v2:
  - Fix value type in device tree bindings:
    aux-devs should be array of phandles without any arguments, so change
    <phandles with arguments> -> <array of phandles>
