Subject: clk: rockchip: rk3399: allow clk_cifout to force clk_cifout_src to reparent

From: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx>

commit 933bf364e152cd60902cf9585c2ba310d593e69f upstream.

clk_cifout is derived from clk_cifout_src through an integer divider
limited to 32. clk_cifout_src is a child of either cpll, gpll or npll
without any possibility of a divider of any sort. The default clock
parent is cpll.

Let's allow clk_cifout to ask its parent clk_cifout_src to reparent in
order to find the real closest possible rate for clk_cifout and not one
derived from cpll only.
