xtensa: fix !CONFIG_XTENSA_CALIBRATE_CCOUNT build failure
Commits 925f5532 (xtensa: ccount based clockevent implementation) and e3f43291 (xtensa: ccount based sched_clock) introduced users of ccount_freq. This variable doesn't exist when CONFIG_XTENSA_CALIBRATE_CCOUNT is disabled. Add ccount_freq definition in this case.
