Subject: [PATCH] cmake: Change the DTS preprocessing work directory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change the DTS preprocessor working directory from the binary
directory to the application directory.

This is done so that the user can specify
-DDTC_OVERLAY_FILE=overlay.dts with a relative path from the
application directory as is possible for CONF_FILE, and as is
reasonably expected to be possible by users.
