Function dt_node_ph_array_prop

This function takes a 'path', property name ('prop'), index ('index') and a cell ('cell') and looks for an EDT node at that path. If it finds an EDT node, it will look to see if that node has a property called 'prop' and if that 'prop' is an phandle-array type. Then it will chec

    This function takes a 'path', property name ('prop'), index ('index') and

    If it finds an EDT node, it will look to see if that node has a property
    called 'prop' and if that 'prop' is an phandle-array type.
    Then it will check if that phandle array has a cell matching the given index
