Alexey Brodkin 4d93617d87 arc: merge common start-up code between ARC and ARCv2
Even though ARCompact and ARCv2 are not binary compatible most of
assembly instructions are used in both. With this change we'll get rid
of duplicate code.

Still IVTs are implemented differently so we're keeping them in separate
files.
