Subject: [PATCH 1/2] ASoC: dt-bindings: fsl,mqs: make gpr optional for SM-based SoCs

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

For SM-based SoCs (i.e. MX95, MX943), GPR configuration is performed by
the SM coprocessor. Thus, the programming model needs no handle to the
GPR node. Make it optional.
