From: Dien Pham <dien.pham...@rvc.renesas.com>
Define OOP tables for all CPUs.
This allows CPUFreq to function.
Based in part on work by Hien Dang.

v3 [Simon Horman]
- Preserve alphabetical order of sub-nodes of root node
- Do not provide unit name for opps, they have no base address
- Describe clock dependency for all CPU cores
v2 [Simon Horman]
- Only provide one operating points node for each operating-points-v2 node
as per the binding; other nodes were unused and have been removed
v1 [Simon Horman]
- consolidated several patches into one
v0 [Dien Pham]
