dt-bindings: pwm: tegra: Add compatible string for Tegra186

Tegra186 has 8 different PWM controllers and each controller has only
one output. Earlier SoC generations have 4 PWM outputs per controller.

Add a device tree compatible string for Tegra186 to be able to
differentiate between the two.

Tegra SoC PWFM controller
Required properties:
- compatible: For Tegra20, must contain "nvidia,tegra20-pwm". For Tegra30,
must contain "nvidia,tegra30-pwm". Otherwise, must contain
"nvidia,<chip>-pwm", plus one of the above, where <chip> is tegra114,
tegra124, tegra132, or tegra210.
- compatible: Must be:
- "nvidia,tegra20-pwm": for Tegra20
- "nvidia,tegra30-pwm", "nvidia,tegra20-pwm": for Tegra30
- "nvidia,tegra114-pwm", "nvidia,tegra20-pwm": for Tegra114
- "nvidia,tegra124-pwm", "nvidia,tegra20-pwm": for Tegra124
- "nvidia,tegra132-pwm", "nvidia,tegra20-pwm": for Tegra132
- "nvidia,tegra210-pwm", "nvidia,tegra20-pwm": for Tegra210
- "nvidia,tegra186-pwm": for Tegra186
- reg: physical base address and length of the controller's registers
- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
the cells format.
