sfc: Own header for nic-specific sriov functions, single instance of netdev_ops and sriov removed from Falcon code

By putting all the efx_{siena,ef10}_sriov_* declarations in
{siena,ef10}_sriov.h, ensure they cannot be called from nic-generic code.
Also fixes up an instance of this, where mcdi.c was calling
efx_siena_sriov_flr.

The single instance of netdev_ops should call general high level
functions that can then call something adapter specific in efx_nic_type.
We should only do adapter specialisation via efx_nic_type.

Removal of sriov functionality from the Falcon code means that tests
are needed for the presence of some callbacks.

- * The PF has access to all 1024 VIs while VFs are mapped to VIs
- * according to VI_BASE and VI_SCALE: VF i has access to VIs numbered
- * in range [VI_BASE + i << VI_SCALE, VI_BASE + i + 1 << VI_SCALE).
- * The number of VIs and the VI_SCALE value are configurable but must
