MOUNT: use a 2nd ext4 partition for /data

To install ev-rom you will need 3 primary partitions on your sdcard.
First fat32, second and third ext4.
Second partition is for NativeSD roms. This setting will not delete
files from the second ext4 partition. This partition is mounted as
/NativeSD.
GPS: Fix missing gps files.
