Added ADSP audio driver support for tegra soc and tegra virt alt. Below are the changes made with respect to Kernel 5.10: - Removed the ADSP COMPR DAI links due to differences in compress DAI link registration in Android (ACK 6.6) which causes build issues. - Omitted the callback function for dumping ADMA registers, as the upstream ADMA driver does not support it. Bug 3910602 Bug 4635899 Change-Id: I63ea878ef2e9a960d127d02470e8048535878518 Signed-off-by: Dara Ramesh <dramesh@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3132128 Reviewed-by: Sameer Pujar <spujar@nvidia.com> GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com>
