ARC-EZchip Shared Auxiliary Registers Per Core

configname: CONFIG_EZNPS_SHARED_AUX_REGS

Linux Kernel Configuration
└─>"EZchip" ARC dev platform
└─>ARC-EZchip Shared Auxiliary Registers Per Core
In linux kernel since version 4.2 (release Date: 2015-08-30)  
On the real chip of the NPS, auxiliary registers are shared between
all the cpus of the core, whereas on simulator platform for NPS,
each cpu has a different set of auxiliary registers. Configuration
should be unset if auxiliary registers are not shared between the cpus
of the core, so there will be a need to initialize them per cpu.
