[oe] Some love for the lvm2 recipes ...

[Simon Busch]

Heyho,

the following patches will update the lvm2 recipe in the oe tree. The first patch rebases
both already available recipes on a general lvm2.inc which contains common stuff for all
lvm2 recipes. The second patch adds a patch to fix a compile issue of both available lvm2
versions. The last two patches introduces machine specific configuration files for lvm2
and add one for the palmpre machine.

regards,
Simon Busch
