Kconfig: fix SYS_CLOCK_HW_CYCLES_PER_SEC dependencies

Browse source 
Fixes the SYS_CLOCK_HW_CYCLES_PER_SEC Kconfig option dependencies such that
it can be overridden by a modified platform configuration file.  This is
particularly important for the LOAPIC timer driver as
SYS_CLOCK_HW_CYCLES_PER_SEC is dependent upon the target's CPU/bus frequency.
