arc: add explicit selection of CPU templates ARC 750D and ARC770D
This separation allows to specify unique options and features for each
CPU.
For example ARC 770D has LLOCK/SCOND instructions built-in by default.
Also this new scheme simplifies selection of proper configuration for
users - preconfigured options now match templates for ARC CPUs.
