arm64: tegra: Fix PCIe regulator for Orin Jetson AGX
The PCIe slot on the Jetson Orin AGX is not working and PCIe cards
are not detected. The regulator for the 3.3V regulator for the PCIe is
using the wrong GPIO for turning on the regulator. Fix this by updating
the 3.3V regulator to use the correct GPIO.
