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 0630/1085] drm/vc4: tests: Add function to lookup a plane for
a CRTC
Some tests will need to find a plane to run a test on for a given CRTC.
Let's create a small helper to do that.
