Álvaro Fernández Rojas 20fe7e687e bcm27xx: update 6.1 patches from RPi foundation
Sync 6.1 patches with the RPi foundation.
Since rpi-6.6.y is now the main branch of the RPi foundation, there won't be
any new patches for linux 6.1.

Subject: [PATCH 1262/1295] Update touch PiTFT overlays
Expose the invert and swap touch parameters on 2.8" and 3.5" resistive touchscreens. Add
the DRM parameter to the PiTFT 2.2" and 2.8" Capacitive overlay in the same
way it is on the resistive overlays. Change the DRM driver to `adafruit,yx240qv29`
because the rotations are consistent with the FBTFT Driver. Fix the override size parameters
on the 2.8" capacitive PiTFT.
