EBB-PRU-Example with kernel 4.4.9 bone10

[Dreambound131]

Hi Derek,
I found that the overlay EBB-PRU-Example(chp13) doesn't work correctly on newer kernel (4.4.9 bone10). In facts the pruss didn't load correctly (no uio) and also pru_pins didn't work. Making some experiments and looking at the cape-universal overlay I made my personal version of EBB-PRU-Example.dts wich works on kernel 4.4.9 bone10 (not sure if it works on older kernels).
Thank you
