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 0489/1085] drm/ili9486: Resolve clash in spi_device_id names
For "Really Good Reasons" [1] the SPI core requires a match
between compatible device strings and the name in spi_device_id.
The ili9486 driver uses compatible strings "waveshare,rpi-lcd-35"
and "ozzmaker,piscreen", but "rpi-lcd-35" and "piscreen" are missing,
so add them.
Compatible string "ilitek,ili9486" is already used by
staging/fbtft/fb_ili9486, therefore leaving it present in ili9486 as an
spi_device_id causes the incorrect module to be loaded, therefore remove
this id.
