pwm: tegra: Add support for Tegra194

Browse Source 
Tegra194 has multiple PWM controllers with each having only one output.

Also the maxmimum frequency is higher than earlier SoCs.

Add support for Tegra194 and specify the number of PWM outputs and
maximum supported frequency using device tree match data.
