[PATCH net-next 01/28] sfc: Disable Siena support

[Martin Habets <habetsm.xilinx@gmail.com>]

From: Martin Habets <martinh@xilinx.com>

Disable the build of Siena code until later in this patch series.
Prevent sfc.ko from binding to Siena NICs.

efx_init_sriov/efx_fini_sriov is only used for Siena. Remove calls
to those.
