[RFC 3/5] of: Return total number of entries in of_count_phandle_with_args

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

of_count_phandle_with_args used to count the phandles until the end of the
list or when the first empty phandle was encountered. There may be valid
entries after the empty phandle as well, include all entries to the count.
