nics: add fm10k module for RedRockCanYou family nic

This module will support fm10k family nics. These nics required special
testpoint for internal switch initialization. Some nics like BulderRapid
must start up testpoint after bound to igb_uio.

Most features like vlan need special configured in testpoint. Those
functions will be realized in fm10k module.
