ARM: dts: Permanently disable hdmi1 and ddc1 on CM4S
CM4S has no HDMI1 output, so it is advisable to disable the controller and its I2C interface in software. This is ordinarily done by setting their status properties to "disabled", but the vc4-kms-v3d(-pi4) overlay enables both HDMIs and DDCs as part of the transfer of control from the VPU. Knobble the CM4S dts in such a way that the overlay applies successfully but the hdmi1 and ddc1 nodes remain disabled by changing the compatible string to something unrecognised.
