        src/sys/arch/arm/omap: am335x_prcm.c am335x_prcm.h omap2_reg.h
        src/sys/arch/evbarm/beagle: beagle_machdep.c

Log Message:
am335x: expect the board code to provide a set_mpu_volt() function,
to change the MPU code voltage. When changing MPU frequency also request
a voltage change. provide frequency/voltage tables for the "blank" revision
and de A revision, based on documents from www.ti.com (this means
it's not possible anymore to request a beaglebone white to run at 1Ghz,
but this was not working anyway).
beagle_machdep.c: callback to the tps65217pmic to change the MPU voltage.

Tested on beaglebone, from 275 to 720Mhz, and on beaglebone black from
300 to 1000Mhz.
