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 1040/1085] dt: Add camX_sync option to configure a GPIO
following cam FS/FE
Unicam now takes an optional GPIO to expose frame start/end timing,
so add an override to configure that.
