[CPUFREQ] Fix exposure of ARM_EXYNOS4210_CPUFREQ

[Russell King - ARM Linux]

From: Russell King <rmk+kernel at arm.linux.org.uk>

exynos4210-cpufreq.c is not buildable on non-exynos builds, so it's
pointless allowing this option to be exposed.  Fix this by adding a
dependency on ARCH_EXYNOS.

drivers/cpufreq/exynos4210-cpufreq.c:20:29: error: mach/regs-clock.h: No such file or directory
drivers/cpufreq/exynos4210-cpufreq.c:21:26: error: mach/cpufreq.h: No such file or directory
