ARM: 5628/1: ep93xx: Introduce Pulse Width Modulator (PWM) driver
The EP93xx features two PWMs (one on the EP9307) with the following
features:
* Configurable dual output
* Separate input clocks for each PWM output
* 16-bit resolution
* Programmable pulse width (duty cycle), interval (frequency), and
polarity
This adds the necessary core support as well as the driver. A sysfs
interface is provided to control the PWM outputs.
