Subject: [PATCH v5] dt-bindings: mfd: qcom,spmi-pmic: add compatibles for audio blocks

If/when pm4125 audio codec will be added to a device tree file, then dtbs
check will emit messages that pmic audio-codec@...0 doesn't match any
of the regexes: '^pinctrl-[0-9]+$'.

Add the compatibles for two possible audio codecs so the devicetree for
such audio blocks of PMIC can be validated properly while also
removing reference to qcom,pm8916-wcd-analog-codec schema file.

Suggested-by: Krzysztof Kozlowski <krzk@...nel.org>
