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 0287/1085] drm/panel: jdi-lt070me05000: Use
gpiod_set_value_cansleep
There is no reason why the control GPIOs for the panel can not
be connected to I2C or similar GPIO interfaces that may need to
sleep, therefore switch from gpiod_set_value to
gpiod_set_value_cansleep calls to configure them.
Without that you get complaints from gpiolib every time the state
is changed.
