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 0747/1085] drm: panel: jdi-lt070me05000: Add
prepare_upstream_first flag
The panel driver wants to send DCS commands from the prepare
hook, therefore the DSI host wants to be pre_enabled first.
Set the flag to achieve this.
