Assemble: add support for RAID0 layouts.
If you have a RAID0 array with varying sized devices
on a kernel before 5.4, you cannot assembling it on
5.4 or later without explicitly setting the layout.
This is now possible with
--update=layout-original (For 3.13 and earlier kernels)
or
--update=layout-alternate (for 3.14 and later kernels)
