Beagle power supply improvements

cwz proposes some Beagle power supply improvements:

* There's no diode steering between DC 5V and USB VBUS
* There's no reason not to be able to use the switcher with both supplies if you have diode steering in there
* When USB VBUS is powering the TPS2141, it can back power directly into the DC 5V rail
* There should be decoupling on SW_IN as well

I created an enhancement issue for this
