ASoC: tegra: Add interconnect support

Browse source 
Add interconnect framework support to set required audio bandwidth
based on PCM device usage. The maximum bandwidth is determined by
the number of APE PCM devices and maximum audio format supported.

If interconnect property is not defined or INTERCONNECT config
is not enabled then the audio usecase will still function.

Validate bandwidth updates by reading the interconnect summary sysfs
node during PCM device open and close operations.
