thermal, cpufreq: Fix build when CPU_FREQ_TABLE isn't configured
Commit 023614183768 ("thermal: add generic cpufreq cooling implementation") requires cpufreq_frequency_get_table(), but that function is only defined for CONFIG_CPU_FREQ_TABLE resulting in the following build error: drivers/built-in.o: In function `cpufreq_get_max_state': drivers/thermal/cpu_cooling.c:259: undefined reference to `cpufreq_frequency_get_table' drivers/built-in.o: In function `get_cpu_frequency': drivers/thermal/cpu_cooling.c:129: undefined reference to `cpufreq_frequency_get_table' Fix it by selecting CONFIG_CPU_FREQ_TABLE for such a configuration. It turns out CONFIG_EXYNOS_THERMAL also needs CONFIG_CPU_FREQ_TABLE, so select it there as well.
