[PATCH 2/2] clk: exynos: do not reparent requested clock

[chiffathefox]

It would appear the original developer of this driver
reparented child clock devices to fix the issue described in
`clk: clk_resolve_parent_clk(): resolve external clocks by id`.
This hacky fix was the cause of invalid memory access when calling
clk_get_rate() on a clock retrieved via clk_get_by_index().
clk_get_by_index() returns a copy of the `struct clk` and
when passed to clk_get_rate() it may be forwarded to
clk_divider_recalc_rate(), which will cause the latter to
run container_of() on a pointer from caller's stack instead
of the pointer that was kzalloc()'d by the clk-divider driver.
