Re: [PATCH v2 3/3] input: touchscreen: ad7879: add device tree support

Add device tree support for the I2C and SPI variant of AD7879(-1).
This allows to specify the touchscreen controller as a I2C client
node or SPI slave device. Most of the options available in platform
data are also available as device tree properties, the only exception
being GPIO capabilities, which can not be activated through device
tree currently.

Changes since v1:
- Move device tree parsing to main driver file ad7879.c
- Use common touchscreen_parse_properties for common properties
- Use device_property_* API
- Use struct ad7879 directly to store parsed values
- Support SPI variant through device tree too (untested)
- Add vendor prefix to vendor specific dt properties
