Subject: yocto-bsp: enable property value display of nested properties

Previous versions of yocto-bsp mapped every input element to a unique
variable name, which is what the current property value display code
expects.  When that was changed to a nested form, the display code
wasn't updated to match - this updated does that.

Fixes [YOCTO #2222]
