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: 0580286d0d22 ("arm64: tegra: Add Tegra234 PCIe C4 EP definition")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
