Subject: [PATCH 07/11] can: lin: Add special frame id for rx offload config

A LIN bus supports up to 64 identifiers in one byte. This commit adds a
special frame ID, beyond the actual LIN identifiers, for signaling RX
offload configuration requests. This ID will be utilized in future LIN
enhancements to the CAN broadcast manager.
