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 1044/1085] ARM: dts: Add strict_gpiod dtparam
Setting strict_gpiod disables the GPIO output persistence, such that
pins are returned to being inputs when they are released. Note that
this applies to the GPIO/pinctrl driver for the user-facing GPIOs,
not the SoC GPIOs on Pi 5.
