This series of patches adds,
- Tegra root port features like Gen2, AER, etc
- Power and perf optimizations
- Fixes like "power up sequence", "dev_err prints", etc

This series of patches are tested on Tegra186 based Jetson-TX2, Tegra210
based Jetson-TX1, T124 based Jetson-TK1, Tegra20 and Tegra30 platforms.

Changes from v4 to v5:
 - Patch [V4, 4/28]: Added blank line before block style comment
 - Patch [V4, 22/28]: "Access endpoint config only if PCIe link is up"
patch is dropped
 - Patch [V4, 27/28]:
* Updated reset gpio toggle logic to reflect active low usage
* Replaced kasprintf() with devm_kasprintf()
* Updated commit message with more information.

Changes from v3 to v4:
 - Patch [V3,27/29] is dropped
 - Patch [V3,28/29]: devm_gpiod_get_from_of_node() is directly used in
   pci-tegra driver instead of of_get_pci* wrapper function defined in
   Patch [V3,27/29].
