After commit 71de0a054d0e ("arm64: tegra: Drop serial clock-names and

error is seen:
serial-tegra 70006300.serial: Couldn't get the reset
serial-tegra: probe of 70006300.serial failed with error -2
Commit 71de0a054d0e ("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 a63c0cd83720c
("arm64: dts: tegra: smaug: Add Bluetooth node") that enabled the HSUART
for the Pixel C. Fix this by populating the "reset-names" property for
the HSUART on the Pixel C.
