Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0812/1085] media: rp1: cfe: Fix error paths in
cfe_start_streaming
Noted that if we get "node link is not enabled", then we also
get the videobuf2 splat for the driver not cleaning up correctly
on a failed start_streaming, and indeed we weren't returning the
buffers.
Checking the other error paths, noted that the "FE enabled, but
FE_CONFIG node is not" path was not calling pm_runtime_put.
Fix both paths.
