regulator: fixed: Remove workaround to handle of_get_named_gpio() return

Browse Source 
The GPIO interface of_get_named_gpio() has implemented the proper
error returns even EPROBE_DEFER and hence caller need not to
implement any workaround for translating the returned error.

Remove the workaround implemented to handle the return of
of_get_named_gpio().
