dts: Add custom bindings directory to builds
This change adds a dts/bindings directory which can be included for
our builds. Normally, we would have to add the dts/bindings
directory to each project. That means that we would need to add
the custom bindings at projects/experimental/volteer/dts/bindings.
This change allows us to add a single location of it instead at the
zephyr-chrome/ level.
The first use case is a custom list of phandles which allows us
to curate the mapping of i2c ports. This will later be used to
move away from our dependency on platform/ec/chip/ files.
