arm64: tegra: Fix HSUART for Jetson AGX Orin

Browse source

After commit 71de0a054d ("arm64: tegra: Drop serial clock-names and
reset-names") was applied, the HSUART failed to probe and the following
error is seen:

 serial-tegra 3100000.serial: Couldn't get the reset
 serial-tegra: probe of 3100000.serial failed with error -2

Commit 71de0a054d ("arm64: tegra: Drop serial clock-names and
reset-names") is correct because the "reset-names" property is not
needed for 8250 UARTs. However, the "reset-names" is required for the
HSUART and should have been populated as part of commit ff578db7b6
("arm64: tegra: Enable UART instance on 40-pin header") that
enabled the HSUART for Jetson AGX Orin. Fix this by populating the
"reset-names" property for the HSUART on Jetson AGX Orin.
