This series adds support for generic binding for pinctrl bcm2835 driver,
and add the code for set output buffer of a pin using the output-low and
output-high generic properties.

Tested on Raspberry Pi Zero W, based on bcm2835 SoC.

Changes since v2:
(Suggested by Eric Anholt)
- Remove PACK and UNPACK macros
- Use pinconf_to_config_* functions
(Suggested by Stefan Wahren)
- Fold Kconfig changes with the driver changes in a single patch
- Add devicetree bindings documentations about generic properties support
- Add devicetree bindings maintainers
