* Rename is_private to is-private as ordered by DT policy.
The change leaves the support for the old format.
* Add is-memcpu property, so it is possible to
enable memory-to-memory transfers support via DT.
* Add hw-llp property, so it is possible to enable
hardware multi block transfers support via DT.
Fix white spaces.
