From: Thierry Reding <treding@nvidia.com>

The AGIC variant of GIC found in the audio subsystem of NVIDIA Tegra186
SoCs is mostly compatible with the version found on Tegra210. Provide a
Tegra210 compatible as a fallback compatible, but also require a
Tegra186 specific compatible for forwards compatibility in case there's
ever a need to implement instantiation-specific quirks.
