dt-bindings: pwm: rcar: Document r8a774[35] PWM bindings
This patch adds compatible strings specific to r8a774[35], no driver change is needed as the fallback compatible string will activate the right code. Also, this patch replaces the example with a DT snippet used for adding PWM0 support to an r8a7743 based platform as the r8a7743 is now the first platform fully compatible with this driver and its PWM DT nodes refer to up-to-date code.
