of: Align macro MAX_PHANDLE_ARGS with NR_FWNODE_REFERENCE_ARGS

Macro NR_FWNODE_REFERENCE_ARGS defines the maximal argument count
for firmware node reference, and MAX_PHANDLE_ARGS defines the maximal
argument count for DT node reference, both have the same value now.

To void argument count inconsistency between firmware and DT, simply
align both macros by '#define MAX_PHANDLE_ARGS NR_FWNODE_REFERENCE_ARGS'.
