[WIP]: v4.19.x-ti remoteproc_pruss changes...

[RobertCNelson]

So, TI's v4.19.x-ti branch just landed TI's remoteproc_pruss changes a few hours ago:

http://git.ti.com/gitweb/?p=ti-linux-kernel/ti-linux-kernel.git;a=shortlog;h=8de817772462078a064b70d368eeae3b92a31439

Right now i don't have a kernel to boot/test, but the pru node changed again, here is the diff:
