net/sfc: fence off 8 bits in Rx mark for tunnel offload

Later patches add support for tunnel offload on Riverhead (EF100).
A board can host at most 254 tunnels. Partially offloaded (missed)
tunnel packets are identified by virtue of 8 high bits in Rx mark.

Add basic definitions of the upcoming tunnel offload support and
take care of the dedicated bits in Rx mark across the driver.

net/sfc: maintain controller to EFX interface mapping

Newer hardware may have arbitrarily complex controller configurations,
and for this reason the mapping has been made dynamic: it is represented
with a dynamic array that is indexed by controller numbers and each
element contains an EFX interface number. Since the number of controllers
is expected to be small, this approach should not hurt the performance.
