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 0958/1085] media: i2c: imx296: Set a 1 frame gain delay
Set the gain delay to 1 frame in the sensor. This avoids any race
condition or ambiguity over when the setting is applied through
userland.
