Linus Walleij d4eaf73b62 ARM: add DT bindings for the ARM11MPCore CPU cluster
The ARM11MPCore has a Snoop Control Unit, but references to it
were missing from the DT specification. Define a compatible
string for this unit.

* ARM Snoop Control Unit (SCU)
As part of the MPCore complex, Cortex-A5 and Cortex-A9 are provided
with a Snoop Control Unit. The register range is usually 256 (0x100)
bytes.

- Cortex-A9: see DDI0407E Cortex-A9 MPCore Technical Reference Manual
Revision r2p0
- Cortex-A5: see DDI0434B Cortex-A5 MPCore Technical Reference Manual

- ARM11 MPCore: see DDI0360F ARM 11 MPCore Processor Technical Reference
Manial Revision r2p0
- compatible : Should be:
"arm,cortex-a9-scu"
"arm,cortex-a5-scu"
"arm,arm11mp-scu"
- reg : Specify the base address and the size of the SCU register window.
Example:
scu@a04100000 {
compatible = "arm,cortex-a9-scu";
reg = <0xa0410000 0x100>;
};
