samsung-zanin: Add device support

The phone boots pmOS, and the basic functionalities are ready.

I will create soon a page on the Wiki:

What's working:

• Flashing with Heimdall (sdcard install)
• USB Network
• Screen
• Boot from sdcard
• Qwerty keyboard (except "Sym" key?)

What's not working:

• Touch (works in ts_test but not in Weston or i3)
• WiFi

Not tested:

• Flashing to internal memory
• Everything else
