Hi all,

This series adds a driver for the Marvell Berlin PWM controller, which
has 4 channels.

This has been tested on a BG2Q DMP.

Thanks,

Antoine

- Reworked the clk enable / clk disable calls
- Removed BERLIN_PWM_DISABLE

Changes since v2:
- Reworked the prescaler/tcnt calculation
- Added an input clock
- Updated the documentation
