[Buildroot] [PATCHv3] beaglebone: add BeagleBone Black support

[Jesse Cobra]

Seems to be working over here for both my BealgeBone white and black.

Beaglebone white boot log:
reading /am335x-bone.dtb
24465 bytes read in 15 ms (1.6 MiB/s)
Booting from ramdisk ...
...
## Flattened Device Tree blob at 80f80000
   Booting using the fdt blob at 0x80f80000
   Loading Kernel Image ... OK
   Loading Ramdisk to 8f2f8000, end 8fa3615a ... OK
   Using Device Tree in place at 80f80000, end 80f88f90
Starting kernel ...
