samsung-coreprimevelte: random fixups
- Fix downstream kernel failing to compile, related to !4539 (merged). While at it, enable PROC_DEVICETREE.
- Move the downstream port to the
unmaintained/
category, as the mainline port is almost as capable (and, in my opinion, still somewhat more usable). - Upgrade the mainline kernel to 6.6, and add patches for Bluetooth and poweroff support.
- Also correct the model name (it's
Samsung Galaxy Core Prime VE LTE
, notSamsung Galaxy Core Prime LTE
).
