[PATCH v3 2/3] arm64: dts: renesas: r8a7795: Add OPPs table for cpu devices

[Simon Horman]

From: Dien Pham <dien.pham.ry at 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]
