Add Mi A2 (Lite) to device list

[KneesDev]

Hi there,

I have found an old bricked Mi A2 Lite and tried unbricking it using your tool as the bootloader is locked, the system is destroyed and recovery sideload is always stuck but I was unable to find any Mi A series devices in the device lists where you're supposed to select your device codename & model.

Could you please add it?
