MIPS: Netlogic: Support for multi-chip configuration
Upto 4 Netlogic XLP SoCs can be connected over ICI links to form a
coherent multi-node system. Each SoC has its own set of on-chip
devices including PIC. To support this, add a per SoC stucture and
use it for the PIC and SYS block addresses instead of using global
variables.
