These casts aren't needed because acb->mem_base0 is a void __iomem *.
You could just do:
reg->cpu_mem_config = acb->mem_base0 +
ARCMSR_ARC1214_CPU_MEMORY_CONFIGURATION;
Or you could change ARCMSR_ARC1214_CPU_MEMORY_CONFIGURATION to:
#define ARCMSR_ARC1214_CPU_MEMORY_CONFIGURATION(acb) (acb->mem_base0 + 0x00008)
So it would be:
reg->cpu_mem_config = ARCMSR_ARC1214_CPU_MEMORY_CONFIGURATION(acb);
