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 0782/1085] media: rp1: csi2: Use standard link_validate
The current csi2_link_validate() skips some important checks. Let's
rather use the standard v4l2_subdev_link_validate_default() as the
link_validate hook.
