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

Browse Source 
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.
