In the resource virtualization unit (RVU) each of the PF and AF (admin function) share a 64KB of reserved memory region for communication. This patch initializes PF <=> AF mailbox IRQs, registers handlers for processing these communication messages. Also adds support to process these messages in both directions ie responses to PF initiated DOWN (PF => AF) messages and AF initiated UP messages (AF => PF). Mbox communication APIs and message formats are defined in AF driver (drivers/net/ethernet/marvell/octeontx2/af), mbox.h from AF driver is included here to avoid duplication. Signed-off-by:
