Message

Add support for Xilinx ZynqMP pinctrl driver and also update the Xilinx
firmware driver to support pinctrl functionality.
This driver queries the pin information from the firmware and allow
configuring the pins as per the request.

changes in v4:
- Added comment for ignoring the return value for GET_FUNCTION_NAME qid.
- Updated the zynqmp_pinctrl_get_function_name() API prototype to void
as it always returns zero.

changes in v3:
- Fixed binding doc comments from Rob.
- Used 'maxItems' for groups and pins properties.
- Updated commit subject and description to have present tense statements.

changes in v2:
- Use pattern for pin names in yaml file.
- Updated to support multiple groups and pins.
- Added type ref for the vendor specific properties.
- Removed 'schmitt-cmos', instead used common properties.
- Removed macros for drive-strength property.
