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 1051/1085] drm/panel: Add and initialise an orientation field
to drm_panel from OF
"rotation" is listed as a standard property of panels in panel-common.yaml,
therefore it would be logical to process that from within the core
code should a panel driver not implement the get_orientation hook.
Call of_drm_get_panel_orientation from
drm_connector_set_orientation_from_panel to get that information.
This removes the need for any boiler-plate in panel drivers for calling
drm_connector_set_orientation_from_panel or
drm_connector_set_panel_orientation.
