aries-common: update lvm partition layout

this patch will wipe the internal sdcard completely.
the internal sdcard will be recognized as an emulated driver on /data partition
the mount point is located /data/media

also, it is creating a dedicated swap partition with 512MB

The new LVM layout:

/data 6GB (shared with new emulated sdcard0)
/system 768MB
/swap 512MB

Inspired by the work of Humberto Borba
Main differences is that /datadata will be kept
