This function is usefull to get phandle number contained in a property list. For example, this allows to allocate the right amount of memory to keep clock's reference contained into the "clocks" property.
To implement it, either of_count_phandle_with_args() or fdtdec_parse_phandle_with_args() are used respectively for live tree and flat tree. By passing index = -1, these 2 functions returns the number of phandle contained into the property list.
Add also the dev_count_phandle_with_args() based on ofnode_count_phandle_with_args()
