Subject: [PATCH v2 RESEND] ASoC: dt-bindings: fsl_spdif: Document imx6sl/sx compatible fallback

From: Fabio Estevam <festevam@...x.de>

i.MX6SL and i.MX6SX SPDIF blocks are compatible with i.MX35.

Document 'fsl,imx35-spdif' as a fallback compatible for these two
chip variants.

This fixes the following dt-schema warnings:

compatible: ['fsl,imx6sl-spdif', 'fsl,imx35-spdif'] is too long
compatible: ['fsl,imx6sx-spdif', 'fsl,imx35-spdif'] is too long

Changes since v1:
