arm64: tegra: Add pinctrl definitions for pcie-ep nodes

Browse source

When the PCIe controller is running in endpoint mode, the controller
initialization is triggered by a PERST# (PCIe reset) GPIO deassertion.

The driver has configured an IRQ to trigger when the PERST# GPIO changes
state. Without the pinctrl definition, we do not get an IRQ when PERST#
is deasserted, so the PCIe controller never gets initialized.

Add the missing definitions, so that the controller actually gets
initialized.

Fixes: 0580286d0d ("arm64: tegra: Add Tegra234 PCIe C4 EP definition")
