cpufreq: Fix build error on some platforms that use cpufreq_for_each_* 

On platforms that use cpufreq_for_each_* macros, build fails if
CONFIG_CPU_FREQ=n, e.g. ARM/shmobile/koelsch/non-multiplatform:

drivers/built-in.o: In function `clk_round_parent':
clkdev.c:(.text+0xcf168): undefined reference to `cpufreq_next_valid'
drivers/built-in.o: In function `clk_rate_table_find':
clkdev.c:(.text+0xcf820): undefined reference to `cpufreq_next_valid'
make[3]: *** [vmlinux] Error 1

Fix this making cpufreq_next_valid function inline and move it to
cpufreq.h.

Fixes: 27e289dce2 (cpufreq: Introduce macros for cpufreq_frequency_table iteration)
