[PATCH v5.1 11/13] of: Add nop implementation of of_get_next_parent()

[Sakari Ailus <sakari.ailus@linux.intel.com>]

of_get_next_parent() was only defined if CONFIG_OF was set. Using the
function thus requires #ifdef CONFIG_OF ... #endif in all cases. Avoid
having to use pre-processor macros around the function by providing a nop
implementation of of_get_next_parent().
