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 0032/1085] drm/vc4: hvs: Move the dlist allocation destruction
to a function
We'll need to destroy a dlist allocation in multiple code paths, so
let's move it to a separate function.
