cpufreq: dbx500: add a Kconfig symbol 

Moving the cooling code into the cpufreq driver caused a possible build failure
when the cpu_thermal helper code is a loadable module or disabled:

drivers/cpufreq/dbx500-cpufreq.o: In function `dbx500_cpufreq_ready':
dbx500-cpufreq.c:(.text.dbx500_cpufreq_ready+0x4): undefined reference to `cpufreq_cooling_register'

This adds the same dependency that we have in other cpufreq drivers,
forcing the driver to be disabled when we can't possibly link it.

Fixes: 19678ffb9f (cpufreq: dbx500: Manage cooling device from cpufreq driver)
