Tegra268 has fewer AHUB interfaces than Tegra264: five RX and five TX
ADMAIF interfaces, five I2S instances, two MVC instances, and one each
of AMX, ADX, MIXER and ASRC.
Add the binding and SoC data with DAI, widget, route and mux tables
matching this topology, so the driver exposes the supported audio paths
and uses the Tegra268 register ranges and source masks.

Tegra268 AHUB supports five RX and five TX ADMAIF interfaces, five
I2S instances, two MVC instances, and one instance each of AMX, ADX,
MIXER and ASRC.
Add the Tegra268 AHUB compatible string to the binding.

Tegra268 AHUB has five RX and five TX ADMAIF interfaces, five I2S
instances, two MVC instances, and one instance each of AMX, ADX,
MIXER and ASRC.
Add Tegra268 support with:
- DAI, DAPM widget and route tables for these audio interfaces.
- Mux controls and register masks covering only supported sources.
- Register access ranges, regmap configuration and SoC match data.
