[U-Boot] [PATCH 04/13] dm: pinctrl: migrate pinctrl-generic to livetree

[Patrick Delaunay]

Migrate pinctrl-generic to livetree:
- ofnode_get_first_property
- ofnode_get_next_property
- ofnode_get_property_by_prop
- ofnode_read_string_count
- ofnode_read_string_index
and get rid of DECLARE_GLOBAL_DATA_PTR.

This solve parsing issue during test in sandbox for pin
configuration (OF_LIVE is activated in sandbox_defconfig
and sub node are not correctly parsed in
pinctrl_generic_set_state_subnode with fdt lib API).
