PATCH v5 1/3 dt-bindings: pwm: tegra: Document Tegra234 pwm binding
Add compatible for nvidia,tegra234-pwm with nvidia,tegra194-pwm as a fallback.
The PWM controller blocks are identical to ones found on the Tegra194 SoC. No driver changes are required and compatible string "nvidia,tegra194-pwm" will be used as a fallback.
