ASoC: tegra-alt: Add support for perf mode

Add support to set minimum online cpu and minimum cpu frequency
through QOS request. If buffer duration for a dai-link is less
than specified latency, minimum online cpu and cpu frequence QOS
requests are issued during corresponding audio playback/capture
session. Fast path latency and minimum online cpu count and cpu
frequency parameters are set through dts file.
