STX Builder 9781c5567d Add the drivers for Silicom STS NICs 
This commit adds the drivers for Silicom STS NICs.
ice driver: 1.10.1.2
iavf driver: 4.6.1
i40e driver: 2.21.12

Now Starlingx supports multiple driver versions as the following.
Currently deployed drivers:(cvl-4.0.1)
ice driver: 1.9.11
iavf driver: 4.5.3
i40e driver: 2.20.12

The Silicom driver version:(cvl-4.10)
ice driver: 1.10.1.2
iavf driver: 4.6.1
i40e driver: 2.21.12

The legacy Intel NIC drivers:(cvl-2.54)
ice driver: 1.5.8.1
iavf driver: 4.0.1
i40e driver: 2.14.13

Testing:
- An ISO image can be built successfully.
- PXE boot-based installation onto an All-in-One Duplex lab was
  successful with rt and std kernels.
- Interfaces are up and pass packets
- Create vfs, ensure that they are picked up by the new iavf
  driver and that the interface can come up and pass packets
- The currently deployed ones are loaded by default and
  the DDP firmware version is correct. It is 1.3.30.0.
- It is possible to switch to the drivers manually with
  command line parameter multi-drivers-switch=cvl-4.10, and the DDP
  firmware version is 1.3.30.0.
- It is also possible to switch back to the currently deployed drivers
  and the legacy drivers manually with command line parameter
  multi-drivers-switch=cvl-4.0.1 and multi-drivers-switch=cvl-2.54.
