[PATCH v1 1/2] dt-bindings: pwm: opencores: Add starfive,jhb100-pwm

[Changhuang Liang]

Add a new compatible string "starfive,jhb100-pwm" for the PWM
controller found on the StarFive JHB100 SoC.

The StarFive JHB100 PWM is based on the OpenCores PWM v1 controller
but with a modification: the polarity has been changed from inverted
to normal. The generic opencores,pwm-v1 hardware only supports
inverted polarity, so the JHB100 variant cannot reuse the
"opencores,pwm-v1" fallback and must be described with a standalone
compatible string.
