This series introduces the driver for the Kona PWM controller found in
Broadcom mobile SoCs like bcm281xx and updates the device tree and the
defconfig to enable use of this hardware on the bcm28155 AP board.

Changes since v1:
  - Fixed up macros to be clearer and more complete
  - Corrected spelling and punctuation mistakes
  - Added support for polarity
  - Made peripheral clock use more efficient
  - Made prescale and duty computation clearer
  - Moved Makefile addition to keep alphabetical
  - Split complex lines into multiple steps
