[PATCH v2 5/7] clk: Use the generic OF phandle parsing in only one place

[Miquel Raynal (Schneider Electric)]

There should be one single entry in the OF world, so that the way we
parse the DT is always the same. make sure this is the case by avoid
calling of_parse_phandle_with_args() from of_clk_get_parent_name(). This
is even more relevant as we currently fail to parse clock-ranges. As a
result, it seems to be safer to directly call of_parse_clkspec() there.
