update_cpu_features: omit more optional arm features

Both on models and architecture levels this time. As part of this, I removed neon from the baseline model because that isn't actually part of the ARMv7 baseline on any platform I'm aware of, and it made our baseline binaries not work on some real boards, e.g. Tegra 2. We keep vfp3d16 since virtually every ARMv7 board has VFP. To not regress PlayStation Vita performance, I also added a kermit model with neon enabled. This was necessary since vortex_a9 lost all NEON/VFP features by default.
