arc: move common sources in library
"reset.c" and "cpu.c" have no architecture-specific code at all. Others are applicable to either ARC CPU. This change is a preparation to submission of ARCv2 architecture port. Even though ARCv1 and ARCv2 ISAs are not binary compatible most of built-in modules still have the same programming model - AUX registers are mapped in the same addresses and hold the same data (new featues extend existing ones). So only low-level assembly code (start-up, interrupt handlers) is left as CPU(actually ISA)-specific. This significantyl simplifies maintenance of multiple CPUs/ISAs.
