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 0437/1085] media: bcm2835-unicam: Start and stop
media_pipeline with same node
media_pipeline_start and media_pipeline_stop now validate that
the pipeline is being started and stopped with the same pipe
and pad handles.
When running with embedded metadata (eg imx477 and imx708), the
start typically happens from the metadata pad, whilst stop is
always from the image pad.
Always pass the image pad to media_pipeline_start to ensure
that the calls are balanced.
