arm64: dts: mediatek: Add MT8186 Voltorb Chromebooks

Add device trees for the MT8186 based Voltorb Chromebooks, also known
as the Acer Chromebook 311 (C723/C723T). The devices are clamshell
style laptops with an optional touchscreen.

The devices differ from the other existing MT8186 Chromebooks in that
it uses a higher speced / binned SoC which also requires a separate
PMIC for the big core cluster. Also, a different codec is used for
the internal speakers.
