add gpio-hog support. GPIO hogging is a mechanism providing automatic GPIO request and configuration as part of the gpio-controller's driver probe function.

Changes in v2:

• move gpio_hog() call from post_probe() to post_bind() call. Check if current gpio device has gpio-hog definitions, if so, probe it.

I am using i2c to gpio chip and with v2 this chip is not listed via dm completely. It means something is wrong for sure. It looks like that parent is not probed that's why it is failing.
