timer: stm32f2xx_timer: add check for prescaler value
The STM32F2XX Timer emulator uses a 16 bit prescaler value to
limit the timer clock rate. It does that by dividing the timer
frequency. If the prescaler 's->tim_psc' was set to be UINT_MAX,
it'd lead to divide by zero error. Limit prescaler value to 16
bits to avoid it.
