[PATCH v4 0/3] Add initial support for TTC PWM driver

[Mubin Sayyed]

Adds initial TTC PWM driver.In case of TTC configured as PWM device,
TTC clocksource driver calls probe of PWM functionality and registers TTC
device with PWM framework.  With these changes drivers/pwm/pwm-cadence.c would be 
part of drivers/clocksource/timer-cadence-ttc.c driver.
