delayMicroseconds(): added support for 1Mhz, 12Mhz and 24Mhz
delayMicroseconds(): added support for 1Mhz, 12Mhz and 24Mhz

1Mhz is a default clock speed on Atmega328, many users run it on the
internal 1Mhz clock to save battery power. Up until now
delayMicroseconds() function wasn't taking this frequencies into an
account.
