This series adds basic support for accessing LVM logical volumes.
Example session:
wkz@spa:~/src/github.com/barebox/barebox$ ./barebox -i
disk0=infix-x86_64.disk,blkdev
[...]
barebox@Sandbox:/ lvm info

#LV: 1
PV disk0.2:

LV "infix-x86_64.raw":

A while back, I sent an RFC of this series [1]. Based on the lack of
critique of the overall structure, I went ahead and added the missing
tests and fixed up the issues it uncovered.
