54a0f730 - [AArch64] Reuse NeoverseN1 and N2 scheduling models for A76/A77/A78. (#211209)

[AArch64] Reuse NeoverseN1 and N2 scheduling models for A76/A77/A78. (#211209) We do not have native scheduling models for some of the Cortex-A generations of CPUs, so they were still using the old Cortex-A57 model. Whilst not perfectly accurate, the NeoverseN1 and NoeverseN2 scheduling models should be a better fit for these CPUs. I mostly just tried to make sure the number of pipelines matches between the neoverse core and the cortex core. If we need something more accurate then we can start adding new models for the CPUs.
