Add support for getting/setting the am335x SoC's internal real time clock. Also, allow the power off alarm to be set. Make readclock an "always on" driver. This is needed for setting power-off alarms whenever the power button is pressed on the BBB. Replace the readclock.sh script & single run driver with a readclock program that takes the same arguments and forwards the requests on to the always up readclock driver.
