dt-bindings: ASoC: admaif: Add missing properties

Add optional interconnect and iommu properties to admaif yaml. These
properties are supported from Tegra186 SoC onwards.

This fixes below dtbs_check error for Tegra194 and Tegra234:
 'interconnect-names', 'interconnects', 'iommus' do not match any of the regexes: 'pinctrl-[0-9]+'
