md: reintroduce md-linear
THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated
CONFIG_MD_LINEAR") because it has been marked as deprecated for a long
time.
However, md-linear is used widely for underlying disks with different size,
sadly we didn't know this until now, and it's true useful to create
partitions and assemble multiple raid and then append one to the other.
People have to use dm-linear in this case now, however, they will prefer
to minimize the number of involved modules.
