pwm: tiecap: Add device-tree binding This patch 1. Add support for device-tree binding for ECAP APWM driver. 2. Set size of pwm-cells set to 3 to support PWM channel number, PWM period & polarity configuration from device tree. 3. Add enable/disable clock gating in PWM subsystem common config space. 4. When here set .owner member in platform_driver structure to THIS_MODULE.
