Moved nfs_diskless setup code from autoconf.c to nfsclient/nfs_diskless.c
so that it is MI. Allow nfs_mountroot to return an error if the nfs_diskless struct is not valid, rather than panicing later on. Call nfs_setup_diskless() from nfs_mountroot if NFS_ROOT is defined, like bootpc_init(). Removed legacy root mount support for sparc64, and enabled NFS_ROOT by default.
