Krzysztof Kozlowski c31844ffdb clk: samsung: Fix double add of syscore ops after driver rebind ...

During driver unbind the syscore ops were not unregistered which lead to
double add on syscore list:

$ echo "3810000.audss-clock-controller" > /sys/bus/platform/drivers/exynos-audss-clk/unbind
$ echo "3810000.audss-clock-controller" > /sys/bus/platform/drivers/exynos-audss-clk/bind
