Subject: [PATCH v3 07/10] ASoC: dt-bindings: qcom,lpass-va-macro: Add missing NPL clock

Several devices (e.g. SC8280XP and SM8450) expect a NPL (Near Pad Logic)
clock.  Add the clock and customize allowed clocks per each variant.
The clocks are also required by ADSP in all variants.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
