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 Signed-off-by: Prodyut Hazarika <phazarika@amcc.com> Signed-off-by: Stefan Roese <sr@denx.de>
