arm64: tegra: Fix RTC aliases

The following warning is observed on the Tegra234 Jetson platforms ...

 rtc-nvidia-vrs10 4-003c: /aliases ID 0 not available

This happens because the 'rtc@c2a0000' device is registered before the
vrs10 RTC and so is assigned the 'rtc0' alias. We want the vrs10 RTC to
be the default RTC because this RTC maintains time across power cycles.
Fix this by adding a 'rtc1' alias for the 'rtc@c2a0000' device.
