Sometimes clocks provided to a consumer might not have .set_rate
operation (like gate or mux clocks), but have CLK_SET_PARENT_RATE flag
set. In that case it's usually possible to find a parent up the tree
which is capable of setting the rate (div, pll, etc). Implement a simple
lookup procedure for such cases, to traverse the clock tree until
.set_rate capable parent is found, and use that parent to actually
change the rate. The search will stop once the first .set_rate capable
clock is found, which is usually enough to handle most cases.

Hi Lukasz, Sean, Tom,
If this patch looks good to you and there are no outstanding comments,
can you please apply it? It's needed as a part of eMMC enablement for
E850-96 board, as eMMC gate (leaf) clock is specified as ciu clock in
dts, which requires further clock rate change propagation up to
divider clock.
Thanks!
Please be patient. The release cycle is quite long. My patch set for HiSilicon
clk framework has been ignored for ~2months already.
Sorry, I've been busy IRL recently.
I will try to review patches in the backlog, but it might be a few more weeks.
