arm64: tegra: Add dmas and dma-names for Tegra234 UARTE

Commit 940acdac99 ("arm64: tegra: Add UARTE device tree node on
Tegra234") added the device tree node for the UARTE on Tegra234 but
didn't include the "dmas" and "dma-names" properties required for this
device when it's used in high-speed mode.
