arm64: dts: apple: Enable DockChannel HID on M2 and later laptops

On M2 and later chipsets, the nodes required to enable
communication with the internal keyboard and trackpad
are disabled by default, this patch enables them only
on laptop (MacBook) variants where this hardware is
actually present.
