From: Thierry Reding <treding@nvidia.com>
Add a driver for the PCIe controller found on NVIDIA Tegra264 SoCs. The
driver is very small, with its main purpose being to set up the address
translation registers and then creating a standard PCI host using ECAM.

---
Changes in v2:
- specify generations applicable for PCI_TEGRA driver to avoid confusion
- drop SPDX-FileCopyrightText tag
- rename link_state to link_up to clarify meaning
- replace memset() by an empty initializer
- sanity-check only enable BAR regions
- bring PCI link out of reset in case firmware didn't
- use common wait times instead of defining our own
- use core helpers to parse and print PCI link speed
- fix multi-line comment
- use dev_err_probe() more ubiquitously
- fix probe sequence and error cleanup
- use DEFINE_NOIRQ_DEV_PM_OPS() to avoid warnings for !PM_SUSPEND
- reuse more standard registers and remove unused register definitions
- use %pe and ERR_PTR() to print symbolic errors
- add signed-off-by from Manikanta as the original author
- add myself as author after significantly modifying the driver

From: Thierry Reding <treding@nvidia.com>
A total of six PCIe controllers can be found on Tegra264. One of them is
used internally for the integrated GPU while the other five can go to a
variety of connectors like full PCIe slots or M.2.
