Note : SH has TIMER_FREQ defined to CPU_FREQ, so any code wanting it must include #config.h before #cpu.h

Put warnings in timer.h for incomplete targets (TIMER_FREQ not defined and/or timer-target.h inexistant)
Correct TIMER_STOP & TIMER_START macros arguments for target without timers
TIMER_START takes an extra argument in multicore builds (macro in macro doesn't work fine..)
