2023-01-12gpio: Get rid of gpio_hog_probe_all()Marek Vasut
The gpio_hog_probe_all() functionality can be perfectly well replaced by DM_FLAG_PROBE_AFTER_BIND DM flag, which would trigger .probe() callback of each GPIO hog driver instance after .bind() and thus configure the hogged GPIO accordingly.

Update the binding file for gpio, it is just an alignment with kernel v5.3. The U-Boot code example for gpio-hog (not directly linked to binding) is moved in a new file doc/README.gpio.
