Subject: [PATCH v4 resend 06/23] i40e: Prep i40e header for aux bus conversion

Add the definitions and private ops to the i40e client
header file in preparation to convert i40e to use
the new auxiliary bus infrastructure. This header
is shared between the 'i40e' Intel networking driver
providing RDMA support and the 'irdma' driver.
