Introduce is_isa_arcv2 and is_isa_arcompact functions. As this functions only check configuration options and return compile-time constant they can be used instead of #ifdef's to to write clear code.
So we can write -------------->8--------------- if (is_isa_arcv2()) ioc_configure(); -------------->8--------------- instead of -------------->8--------------- ifdef CONFIG_ISA_ARCV2 ioc_configure(); endif -------------->8---------------
