cpufreq: exynos: remove Exynos4210 specific cpufreq driver support

Exynos4210 based platforms have switched over to use generic cpufreq driver for cpufreq functionality. So the Exynos specific cpufreq support for these platforms can be removed. Changes by Bartlomiej: - dropped Exynos5250 support removal for now - updated exynos-cpufreq.[c,h] Cc: Javier Martinez Canillas <[email protected]> Acked-by: Viresh Kumar <[email protected]> Signed-off-by: Thomas Abraham <[email protected]> Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]> Signed-off-by: Michael Turquette <[email protected]>
