Merge branch 'rproc-linux-4.1.y' of git://git.ti.com/rpmsg/remoteproc into rpmsg-ti-linux-4.1.y

Pull in the updated remoteproc feature branch that includes various
cleanups on the PRUSS remoteproc driver, and fixes couple of issues.
The cleanup also includes splitting up the current pruss_remoteproc.c
file into two files and modules, one per platform driver.

The new modules that will be build are pruss.ko and pru_rproc.ko,
and these replace the previous module pruss_remoteproc.ko.
