Get rid of CONFIG_LSF
We have two seperate config entries for large devices/files. One
is CONFIG_LBD that guards just the devices, the other is CONFIG_LSF
that handles large files. This doesn't make a lot of sense, you typically
want both or none. So get rid of CONFIG_LSF and change CONFIG_LBD wording
to indicate that it covers both.

This option is required to support the full capacity of large
(2TB+) block devices, including RAID, disk, Network Block Device,
Logical Volume Manager (LVM) and loopback.
