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 0703/1085] dts: bcm2712-rpi-5-b: Create some dummy nodes
The kernel now treats multiple fragments targeting the same node as an
error. For this reason, it is important that labels created just for
compatibility with other systems (e.g. i2c0if and i2c0mux) are
attached to unique nodes, not just tacked onto existing nodes.
