ARC: Introduce is_isa_X() functions
Introduce is_isa_arcv2() and is_isa_arcompact() functions.
These functions only check configuration options and return
compile-time constant so they can be used instead of #ifdef's to
to write cleaner code.
Now we can write:
-------------->8---------------
if (is_isa_arcv2())
ioc_configure();
-------------->8---------------
instead of:
-------------->8---------------
ifdef CONFIG_ISA_ARCV2
ioc_configure();
endif
-------------->8---------------
