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.

ARM: dts: am335x-bone*: Fix model name and update compatibility information Beaglebone white and beaglebone black differ in tiny little aspects. This is the reason why we maintain seperate dts for these platforms. However, there is no real way to decode from dtb which platform it is since compatible and model name are the same for both platforms. Fix this so that beaglebone black and beaglebone are identifiable, while maintaining compatibility for older zImages which might use old beaglebone compatible flag for black as well.
