PRUSS doesn't work well

[YuryAlkevich]

This issue has already been on 3.8 kernel
beagleboard/kernel#37
Anytime I try to enable pruss via .dtbo I get
pruss_uio 4a300000.pruss: No children
If found out that source code (uio_pruss.c) for pruss driver on kernel 3.8 is different from kernel 4.1. And pruss doesn't throw error when there is no child nodes in pruss node of dts file on 3.8. Initialization won't continue after this error, but i guess pruss driver should work well without any children nodes in dts file.

I think that patch made it back in somehow. I use the PRU and was able to fix it by adding some "children" pins to my overlay, but it clearly should be "fixed again"?
