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 1103/1135] drm/bridge: panel: Name an associated backlight
device
Pass the DRM connector name to any configured backlight
device so that userspace can associate the two items.
Ideally this should be in drm_panel, but it is bridge/panel
that creates the drm_connector and therefore knows the name.
