reset: Return -ENOTSUPP when not configured
Prior to commit 6c96f05c8bb8 ("reset: Make [of_]reset_control_get[_foo]
functions wrappers"), the "optional" functions returned -ENOTSUPP when
CONFIG_RESET_CONTROLLER was not set.
Revert back to the old behavior by changing the new
__devm_reset_control_get() and __of_reset_control_get() functions to
return ERR_PTR(-ENOTSUPP) when compiled without CONFIG_RESET_CONTROLLER.
Otherwise they will return -EINVAL causing users to think that an error
occurred when CONFIG_RESET_CONTROLLER is not set.
Fixes: 6c96f05c8bb8 ("reset: Make [of_]reset_control_get[_foo] functions wrappers")
