This series adds support for the pruss/pru_rproc drivers on am33xx and
am57xx SoCs.

All PRU interfaces pru0 and pru1 are supported on am33xx.
All PRU interfaces pru0, pru1, pru2, and pru3 are supported on am57xx.

Testing is done via the "rproc" U-Boot command.

This patch series is based on ti-u-boot-2020.01 branch on ti-u-boot
repository located at: https://git.ti.com/cgit/ti-u-boot/ti-u-boot/
and commit 2781231a33c3
("arm: mach-k3: j721e_init: probe clock node after sci node is probed")

>From looking at the master branch of the main u-boot repository, there does
not appear to be significant effort required to merge it into the master
