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 0946/1085] drm/panel: ilitek-ili9881c: Allow configuration of
the number of lanes
Not all panels use all 4 data lanes, so allow configuration based
on the compatible string.
