cmake: DT: Add support for overlays that reference board-provided dtsi

Add BOARD_DIR to DTS_ROOTS so these shared files can be located when
included from application-specific overlays.

DeviceTree Definitions
======================
Additional DeviceTree directory trees, or DTS_ROOTs, can be added by
creating this directory tree::
DeviceTree directory trees are found in ``APPLICATION_SOURCE_DIR``,
``BOARD_DIR``, and ``ZEPHYR_BASE``, but additional trees, or DTS_ROOTs,
can be added by creating this directory tree::
dts/bindings/

dts/common/
dts/arm/

dts/bindings/
Where 'arm' is changed to the appropriate architecture. Each directory
is optional. The binding directory contains bindings and the other
