[PATCH 2/3] arm64: tegra: Add PWM nodes on Tegra186

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

These PWMs can be used for fan or LED backlight control. Add the device
tree nodes for all existing controllers found on Tegra186 SoCs. None of
these are enabled by default, which is left for the board DTS files to
do when necessary.
