samsung-codina: new device (Samsung Galaxy Ace 2)

Samsung Galaxy Ace 2 PostmarketOS port.

Wiki: https://wiki.postmarketos.org/wiki/Samsung_Galaxy_Ace_2_(samsung-codina)

What works:

• Flashing
• Touchscreen
• Battery
• Display
• Weston
• charging-sdl

What definitely doesn't:

• USB network
• WiFi
• Bluetooth
• heimdall-isorec(kernel fails booting)

This port was made using existing(samsung-golden and samsung-i9070) NovaThor U8500 ports. I've just tuned it a little bit for this device.

I need to fix USB somehow, it looks like it's different from samsung-i9070. I can't really do checks or anything on the device(typing on 3.5 display is AWFUL). It is completely non-detectable by PC. Is there any known USB bugs on these devices? Or maybe something is wrong with my config(this is more likely)?
