Adds initial TTC PWM driver. New driver would use same compatible string
as that of drivers/clocksource/timer-cadence-ttc.c.

Specific TTC device would be identified as clocksource/clockeven or PWM
device based on the pwm-cells poperty. Clocksource TTC driver checks for
pwm-cells property, if found, it just returns without acting on it.

  clocksource: timer-cadence-ttc: Do not probe TTC device configured as
    PWM
  dt-bindings: timer: Add bindings for TTC PWM
  pwm: pwm-cadence: Add support for TTC PWM
