[0/4] AM57xx: PRU ICSS Support

Message

Hi,

This series adds PRU-ICSS support for AM57xx IDK.

PRU-ICSS is not present only on AM57xx SoCs so the PRUSS
nodes are left disabled in dra7.dtsi. The board that uses
a AM57xx SoC will have to enable them if required.

PRU-ICSS has a SYSC register but it requires custom handling.
So we add a new "ti,sysc-pruss" type to the ti-sysc bus driver.

This series depends on 

[1] - PRU ICSS support v2
 https://lkml.org/lkml/2019/2/4/677

cheers,
