arc: add dependences on MMU presence Depending on MMU presence in CPU there're differences in HW behavior. For example address of instruction that caused exception is put in ECR register if MMU exists and in ERET register otherwise.

arc: add more flavours of ARC700 series CPU Now we may select a particular version of ARC700: * ARC750D or * ARC770D It allows more flexible (or more fine tuned) configuration of U-Boot. Before that change we relied on minimal configuration but now we may use specific features of each CPU. Moreover allows us to escape manual selection of options that exist in both CPUs but may have say different version like MMUv2 in ARC750D vs MMUv3 in ARC770D.
