mediatek: disable MediaTek SoC Information (mtk-socinfo) driver

With the switch to Linux 6.12 this driver was enabled by accident.
However, it doesn't support any of the router SoCs but is meant to be
used only by the smartphone, tablet and chromebook SoCs.
Disable the driver again to silence a kernel error logline during boot.
