Move all patch that got merged upstream from pending to backport and add related tag. This is to make it easier to update to kernel 6.12. Patch 680 required some special care as the upstream version had to be split in a series of 6 patch. Referesh all affected patch.

+description: |
|
|
+ The Raspberry Pi PiSP Image Signal Processor (ISP) Back End is an image
|
|
+ processor that fetches images in Bayer or Grayscale format from DRAM memory
|
|
+ in tiles and produces images consumable by applications.
|
|
