ppc4xx: Optimize PLB4 Arbiter and Memory Queue settings for PPC440SP/SPe,
PPC405EX and PPC460EX/GT/SX
- Read pipeline depth set to 4 for PPC440SP/SPE, PPC405EX, PPC460EX/GT/SX
processors
- Moved PLB4 Arbiter register definitions to ppc4xx.h since it is shared
across processors (405 and 440/460)
- Optimize Memory Queue settings for PPC440SP/SPE and PPC460EX/GT/SX
processors
- Add register bit definitions for Memory Queue Configuration registers
