In conjunction with seL4/rust-sel4#316 allows for using the fpu flag to specify that a PD can be using the FPU.

There is a good reason why I made the FPU enabled by default.

If you do disable it by default, you better give a big warning that people should compile the code with -mgeneral-regs-only, otherwise they'll get crashes.

Yes. Now it's enabled by default.

Main issue is rust-sel4 PR, otherwise this is pretty trivial.

For now I can merge the FPU changes into our rust-sel4 branch for development, but we'll need to merge that PR before the release.
