Rationale: The differences between Falcon and Siena are in many ways larger than those between Siena and EF10 (despite Siena being nominally "Falcon- architecture"); for instance, Falcon has no MCPU, so there is no MCDI. Removing Falcon support from the sfc driver should simplify the latter, and avoid the possibility of Falcon support being broken by changes to sfc (which are rarely if ever tested on Falcon, it being end-of-lifed hardware). The sfc-falcon driver created in this changeset is essentially a copy of the sfc driver, but with Siena- and EF10-specific code, including MCDI, removed and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000- series") to avoid collisions when both drivers are built-in. This changeset removes Falcon from the sfc driver's PCI ID table; then in sfc I've removed obvious Falcon-related code: I removed the Falcon NIC functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything that referenced them. Also, increment minor version of both drivers (to 4.1). For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs doesn't cause Falcon support to disappear; but that should be undone at some point in the future.
