Subject: [PATCH 3/5] dt-bindings: pwm: sun20i: Add compatible string for Allwinner H616 PWM

Allwinner H616 SoC has a PWM controller similar to the one
in the D1, which is supported by the pwm-sun20i driver.

The main difference is in the register layout. Specifically, the
GATING flag is placed in the PCCR register instead of the
individual PCGR register.

Add a compatible string to distinguish them.
