From: "Andrew F. Davis" <afd@xxxxxx>
Add two new API - pruss_request_mem_region() & pruss_release_mem_region(),
to the PRUSS platform driver to allow client drivers to acquire and release
the common memory resources present within a PRU-ICSS subsystem. This
allows the client drivers to directly manipulate the respective memories,
as per their design contract with the associated firmware.

Why don't we just put these definitions in the correct header file
to start with when they are introduced earlier in this series?
