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.
