arm64: tegra: Correct Tegra132 I2C alias

There is no such device as "as3722@40", because its name is "pmic".  Use
phandles for aliases to fix relying on full node path.  This corrects
aliases for RTC devices and also fixes dtc W=1 warning:

  tegra132-norrin.dts:12.3-36: Warning (alias_paths): /aliases:rtc0: aliases property is not a valid node (/i2c@7000d000/as3722@40)

Fixes: 0f279ebdf3ce ("arm64: tegra: Add NVIDIA Tegra132 Norrin support")
