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 0593/1085] drm/vc4: plane: Change ptr0_offset to an array
The BCM2712 will have a fairly different dlist, that will feature one
Pointer 0 word for each plane.
Let's prepare by changing the ptr0_offset variable that holds the offset
in a dlist of the pointer 0 word to an array.
