This is exactly the case that Dmitry is trying to solve. The problem
is that bcm63xx
and lantiq set CONFIG_HAVE_LEGACY_CLK but lack the clk_set_parent()
and clk_get_parent() functions. We could add the same stubs for these
two that we have for the other legacy clk implementations, or rework the
handling of legacy clocks completely.
