Subject: [PATCH 02/11] ASoC: dt-bindings: allwinner,sun4i-a10-i2s: Add compatible for A523

As far as the author can tell, based on their respective manuals,
the I2S interface controllers found in the Allwinner A523 SoC is the
same as ones in the R329 SoC.

Add a SoC-specific compatible for it, with a fallback to the R329's
compatible.
