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 0609/1085] drm/vc4: drv: Support BCM2712
The BCM2712 has an improved display pipeline, most notably with a
different HVS and only HDMI and writeback outputs.
Let's introduce it as a new VideoCore generation and compatible.
