of: property: fw_devlink: Add a devlink for panel followers

Browse Source 
commit fbf0ea2da3c7cd0b33ed7ae53a67ab1c24838cba upstream.

Inform fw_devlink of the fact that a panel follower (like a
touchscreen) is effectively a consumer of the panel from the purposes
of fw_devlink.

NOTE: this patch isn't required for correctness but instead optimizes
probe order / helps avoid deferrals.
