[PATCH 1/3] ASoC: dt-bindings: qcom,wcd93xx-common: don't require micbias4

[Jorijn van der Graaf]

The WCD9370/9375, WCD9380/9385 and WCD9390/9395 codecs all have four
mic bias supplies, but the upcoming WCD9378 only has three, so it
cannot reference the common schema while qcom,micbias4-microvolt is
required there. Move that requirement out of the common schema into
each of the current users; no binding is relaxed by this.
