[arm] Add default FPUs for CPUs.

This patch adds the default CPUs for each cpu and provides options for
changing the FPU variant when appropriate.

It turns out to be easier to describe removal options using general
mask operations that disable a concept rather than specific bits.
Sometimes the helper definitions for enabling a feature are not excat
duals when it comes to disabling them - for example, +simd forcibly
turns on double-precision capabilities in the FPU, but disabling just
simd (+nosimd) should not forcibly disable that.
