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.

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.
