Subject: [PATCH v2 1/2] ASoC: dt-bindings: lpass-va: add npl clock for new VA macro

LPASS VA Macro now has soundwire master to deal with access to
analog mic in low power island use cases. This also means that VA macro
now needs to get hold of the npl clock too. Add clock bindings required
for this.

As part of adding this bindings, also update bindings to be able to
specific and associate the clock names specific to the SoC.
