[DevKit] Touchscreen does not work with default configuration.

[Denix]

I am using RaspianOS 12 with kernel 6.6.28+rpt-rpi-v8
To enable touchscreen in DevKit I had to comment line

#dtoverlay=vc4-kms-v3d

and add line:

dtoverlay=vc4-fkms-v3d

is this necessary for the Mark2 ? if yes, can we add this to the ansible?

Mark II doesn't need vc4-fkms-v3d which is good as vc4-fkms-v3d (Fake KMS) is getting less attention from the Raspberry Pi developers as their focus is now more for on the Full KMS implementation.

raspberrypi/documentation#2310

We could find a way to detect both, DevKit is running version 06 of SJ201 as Mark II is running version 10. If version 06 is detected then we can replace vc4-kms-v3d by vc4-fkms-v3d.
