Add support for Xiaomi Redmi 7 (onclite)

[barni2000]

Initial support for Redmi 7, maybe these changes fine for Y3 also.
It needs custom dtbo image https://github.com/barni2000/dtbo-onclite

I have removed all the node what is not need for the boot but the remaining nodes are needed.

This is with erased/empty dtbo partition or not? Curious if the bootloader itself actually uses some of these nodes, on SDM632 Fairphone 3 it doesn't need anything but since the bootloader is buggy a fully empty dtbo image will crash, so this is needed: https://github.com/z3ntu/dtbo-fp3
