[PATCH v1 06/14] extcon: Allow name to be assigned outside of the framework

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

The documentation states that name of the extcon can be assigned
outside of the framework, however code does something different.
Fix the code to be aligned with the documentation.
