fit: Add "board-skuX" (without -rev) to allowed compatible strings

In some cases we may have boards that need to differentiate SKUs but
don't really want to differentiate revisions (at least for some SKUs).
Let's add a compatible string match that includes only the SKU but not
the revision so that kernel DTSes don't have to specify every possible
revision if they want to match this.

This patch was adapted from depthcharge's http://crosreview.com/1512004
