ASoC: sun4i-i2s: Update binding documentation to include A31
Add a new compatible for sun4i-i2s driver to handle some
SoCs that have a reset line that must be asserted/deasserted.
This new compatible, "allwinner,sun6i-a31-i2s", requires the
property "resets" which should be a phandle to the reset line.
Except these differences, the compatible is identical to previous one
which will not handle a reset line.
