[PATCH v5 2/2] dt-bindings: sound: tlv320aic3x: Add optional clock and port properties

[Jai Luthra]

Describe optional properties for clocks and ports that were missing in
the original txt binding, to fix warnings like:

aic33 at 18: 'assigned-clock-parents', 'assigned-clock-rates',
	'assigned-clocks' do not match any of the regexes:
	'pinctrl-[0-9]+'
	arch/arm/boot/dts/omap2420-n810.dtb

tlv320aic3106 at 1b: 'port' does not match any of the regexes: 'pinctrl-[0-9]+'
	arch/arm/boot/dts/am335x-sl50.dtb

codec at 18: 'clocks' does not match any of the regexes: 'pinctrl-[0-9]+'
	arch/arm/boot/dts/imx6dl-gw5903.dtb
	arch/arm/boot/dts/imx6q-gw5903.dtb
