Kevin Kim 620bc954fc pwm: gpio: Add a generic gpio based PWM driver ...

From: Olliver Schinagl <oliver@schinagl.nl>

This patch adds a bit-banging gpio PWM driver. It makes use of hrtimers,
to allow nano-second resolution, though it obviously strongly depends on
the switching speed of the gpio pins, hrtimer and system load.

Each pwm node can have 1 or more "pwm-gpio" entries, which will be
treated as pwm's as part of a pwm chip.
