[dts] [PATCH 4/8] nics: add fm10k module for RedRockCanYou family nic

[Yong Liu]

From: Marvin Liu <yong.liu at intel.com>

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.
