Subject: [PATCH V4 15/16] ARM64: tegra: Add audio PM domain device node for Tegra210

Add the audio power-domain for tegra210. Note that this also removes the
existing "#power-domain-cells" which was incorrectly included by
commit e53095857166 ("arm64: tegra: Add Tegra210 support").

Signed-off-by: Jon Hunter <jonathanh@...dia.com>

---

So far I have only added the audio power-domain for tegra210 as this is
what I have been testing with to date. However, once this series is
accepted then we can begin to add more.
