[Qemu-ppc] [PULL 08/44] target/ppc: Add ibm, purr and ibm, spurr device-tree properties |

From: Suraj Jitindar Singh <address@hidden>
The ibm,purr and ibm,spurr device tree properties are used to indicate
that the processor implements the Processor Utilisation of Resources
Register (PURR) and Scaled Processor Utilisation of Resources Registers
(SPURR), respectively. Each property has a single value which represents
the level of architecture supported. A value of 1 for ibm,purr means
support for the version of the PURR defined in book 3 in version 2.02 of
the architecture. A value of 1 for ibm,spurr means support for the
version of the SPURR defined in version 2.05 of the architecture.
Add these properties for all processors for which the PURR and SPURR
registers are generated.
