When a clock, C is initialised any orphan clocks listing C as
a possible parent are reparented to it regardless of the
parent requested by the orphan's get_parent() operation.
This means that multiplexers registered before their parents
are reparented to the first parent subsequently declared,
regardless of the selection made by the hardware registers.
For example:
static const char *sel[] = { "srcA", "srcB", "dummy", "srcC" };
child = clk_register_mux(NULL, "child", sel, ARRAY_SIZE(sel), ...);
clk_register_fixed(NULL, "dummy", ...);
clk_register_fixed(NULL, "srcA", ...);
clk_register_fixed(NULL, "srcB", ...);
clk_register_fixed(NULL, "srcC", ...);
Causes child's parent to always be "dummy".
To fix this, when an orphanned clock has a get_parent() operation,
only reparent to the clock indicated by get_parent().
