NFS: Use super.c for NFSROOT mount option parsing
Replace duplicate code in NFSROOT for mounting an NFS server on '/' with logic that uses the existing mainline text-based logic in the NFS client. Add documenting comments where appropriate. Note that this means NFSROOT mounts now use the same default settings as v2/v3 mounts done via mount(2) from user space. vers=3,tcp,rsize=<negotiated default>,wsize=<negotiated default> As before, however, no version/protocol negotiation with the server is done.
