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---------------
