onclite: Set device model based on hwversion

* Redmi 7 and Redmi Y3 are nearly same device except Front camera and Gyroscope sensor.
* Redmi Y3 has 32MP selfie camera that is an AUX camera which is a cursed part in custom roms.
  And Gyroscope sensor works well in Y3 since we are including permission config which won't affect Redmi 7 as well
* Hence, Redmi Y3 is an another variant of Redmi 7.
  Lets set the correct device name based on hwversion in init.
