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 0321/1085] drivers: bcm2835_unicam: Add logging message when a
frame is dropped.
If a dummy buffer is still active on a frame start, it indicates that this frame
will be dropped. The explicit logging helps users identify performance issues.
