mb/google/{rex, ovis}: Introduce devicetree.cb for pre-prod SoC

This patch introduces a dedicated devicetree.cb file for platforms
built with pre-production SoC. This will help to keep the SoC
configuration separate for platforms with ESx and QSx silicons.

For example, the SaGv WP configuration is different between
pre-production (aka ESx) and production (aka QSx) silicon.
