[Nuvoton] Enlarge LPTICKER_DELAY_TICKS for safe

On Nuvoton targets, lp_ticker_set_interrupt(...) needs around 3 lp-ticker
ticks to take effect. It may miss when current tick and match tick are very
close (see hal/LowPowerTickerWrapper.cpp). Enlarge LPTICKER_DELAY_TICKS to
4 from 3 to address this boundary case.
