Documentation/arm64: update memory layout table.

Commit b89ddf4cca43("arm64/bpf: Remove 128MB limit for BPF JIT programs")
removes the bpf jit region from the memory layout of the Aarch64
architecture. However, it forgets to update the documentation
accordingly.

- Remove the bpf jit region.
- Fix the Start and End addresses of the modules region.
- Fix the Start address of the vmalloc region.
