Subject: [PATCH 1/2] thermal: TI: remove TI_THERMAL dependency on CPU_THERMAL

Cover cpufreq_get_current_driver() call in ti-thermal-common.c with
CPU_FREQ ifdefs and remove no longer needed CPU_THERMAL dependency
from TI_THERMAL config option (stubs for other cpufreq functions for
CPU_THERMAL=n case are already available).

Please note that this enables TI_THERMAL config option in the final
config derived from omap2plus_defconfig (which enables CPU_THERMAL
config option but without CPU_FREQ one so TI_THERMAL config option
was not enabled previously in the final config).
