arm64: dts: mediatek: Introduce MT8186 Steelix 

The MT8186 Steelix, also known as the Lenovo 300e Yoga Chromebook Gen 4,
is a convertible device based on a common design of the same name. The
device comes in different variants. Of them, whether a world facing
camera is integrated is the only differentiating factor between the
two device trees added. The different SKU IDs describe this alone.

The other device difference is the trackpad component used. This is
simply handled by having both possible components described in the
device tree, and letting the implementation figure out which one is
actually available. The system bootloader / firmware does not
differentiate this in that they share the same SKU IDs.
