Krzysztof Kozlowski b7c51fb4c1 clk: samsung: fix getting Exynos4 fin_pll rate from external clocks 
commit f99b3feb3b0e9fca2257c90fc8317be8ee44c19a upstream.

Commit 0dc83ad8bfc9 ("clk: samsung: Don't register clkdev lookup for the
fixed rate clocks") claimed registering clkdev lookup is not necessary
anymore, but that was not entirely true: Exynos4210/4212/4412 clock code
still relied on it to get the clock rate of xxti or xusbxti external
clocks.

Drop that requirement by accessing already registered clk_hw when
looking up the xxti/xusbxti rate.
