v6.35

+ DietPi-Set_hardware | RPi: Do not add device tree overlays or parameters at runtime. We already know that this does not work in most cases but a reboot is required. + DietPi-Set_hardware | RPi4: The VC4 full KMS driver on RPi 4 additionally blocks card 1 with additional sound devices for the second HDMI port. Increment the target sound card hence additionally by 1 if this driver is enabled.
