[PATCH v3 01/21] dm: pinctrl: convert pinctrl-single to livetree

[Patrick Delaunay]

Convert 'pinctrl-single' using livetree functions
- dev_read_prop
- dev_read_u32_default
- dev_read_u32_array
- dev_read_bool
- dev_read_addr
and get rid of DECLARE_GLOBAL_DATA_PTR.

Changes in v3: None
Changes in v2:
- use the dev_ API instead of ofnode_ function.
