mb/google/kahlee/liara/devicetree: move Raydium touchscreen to baseboard
Move the Raydium touchscreen to the baseboard devicetree. Since only the
liara variant uses a level IRQ as I2C devices are supposed to, all other
board variants still override this to use an edge IRQ which were added
as a workaround to make the touchscreen work on the other devices. Right
now it's unclear to me if that edge IRQ workaround was only needed
temporarily and can now be removed, so I'll keep it as it was for now.
If this turns out to be no longer needed on the other variants, the
overrides can be dropped in the future.
