blkcg: mark existing cftypes as legacy
blkcg is about to grow interface for the unified hierarchy. Add
legacy to existing cftypes.
* blkcg_policy->cftypes -> blkcg_policy->legacy_cftypes
* blk-cgroup.c:blkcg_files -> blkcg_legacy_files
* cfq-iosched.c:cfq_blkcg_files -> cfq_blkcg_legacy_files
* blk-throttle.c:throtl_files -> throtl_legacy_files
Pure renames. No functional change.
