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 0565/1085] dmaengine: bcm2835: Rename to_bcm2711_cbaddr to
to_40bit_cbaddr
As the shifted address also applies to bcm2712,
give the function a more specific name.
