This patch series adds DDR performance monitor support
on Marvell cn10k series of processor.

First patch adds device tree binding changes.
Second patch add basic support (without overflow and event
ownership). Third and fourth patch adds overflow and event
ownership respectively.

Seems like 4th patch can be merged in second patch,
For easy review it is currently separate
