doc: scripts: gen_devicetree_rest: add workaround for page width

Since Zephyr docs switched to fixed-width, the binding pages are not
displayed correctly. We should move to another data representation
format that works better for fixed-width documents. Until this decision
is made, add a workaround that forces the template to expand page width
to the maximum on binding pages.
