In order to have that correctly propagated, you should register a new
mux here in the clock framework, and have all the other clocks using
that mux as a parent.

I agree. Checking the diagram in subsection 1.5.2 of the A20
manual it seems, that LOSC can be a source for clocks like CPU and
some SoC busses. So my patch could indeed mess with the whole
clock tree.

Within the current sunxi clk structure, the LOSC is registered as a fixed
32.768 KHz clk. So this patch actually makes things right.

On the condition that the driver gets loaded, which is not guaranteed.
