ARM: dts: am335x-bone*: add DT for BeagleBone Black
The BeagleBone Black is basically a regular BeagleBone with eMMC and HDMI added, so create a common dtsi both can use. IMPORTANT: booting the existing am335x-bone.dts will blow up the HDMI transceiver after a dozen boots with an uSD card inserted because LDO will be at 3.3V instead of 1.8. MMC support for AM335x still isn't in, so only the LDO change has been added.
