arm64: dts: mediatek: mt8395-genio-1200-evk: Disable unused backlight

The builtin panel on the Genio 1200 EVK board uses the backlight_lcm0
node for its backlight. Though the backlight_lcd1 is currently left
enabled, it is unused, and its pwm input, disp_pwm1, is disabled, so it
fails probe. Disable this unused node.
