Cadence TTC can act as PWM device, it will be supported through
separate PWM framework based driver. Decision to configure
specific TTC device as PWM or clocksource/clockevent would
be done based on presence of "#pwm-cells" property.
Also, interrupt property is not required for TTC PWM driver.
Update bindings to support TTC PWM configuration.
