reset: add exported __reset_control_get, return NULL if optional
commit 62e24c5775ecb387a3eb33701378ccfa6dbc98ee upstream.
Rename the internal __reset_control_get/put functions to
__reset_control_get/put_internal and add an exported
__reset_control_get equivalent to __of_reset_control_get
that takes a struct device parameter.
This avoids the confusing call to __of_reset_control_get in
the non-DT case and fixes the devm_reset_control_get_optional
function to return NULL if RESET_CONTROLLER is enabled but
dev->of_node == NULL.
Fixes: bb475230b8e5 ("reset: make optional functions really optional")
