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 0487/1085] drivers: media: imx296: Add standby delay during
probe
Add a 2-5ms delay when coming out of standby and before reading the
sensor info register durning probe, as instructed by the datasheet. This
standby delay is already present when the sensor starts streaming.
