And as someone having been involved with review of a few different
UFS provisioning bits this is what I think we should be merging.

Instead of being in a rat race of adding ever new sysfs or configfs
attributes for things that don't matter to normal driver operation
I'd rather have a relatively clean pass through interface and move
policy to userspace.  Especially given that there are plenty of
vendor specific commands at these levels as well.
