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 two
properties:
	- resets: phandle to the reset line
	- reset-names: the name of the reset line ("rst").
Except these differences, the compatible is identical to previous one
which will not handle a reset line.
