[dts] [PATCH v2 04/28] framework crb: Appending only 10G devices for cavium

[Angela Czubak <aczubak@caviumnetworks.com>]

When collecting pci devices info in
pci_devices_information_uncached_linux devices are checked if they are
from cavium and if so linkspeed is detected to append only 10Gb
interfaces
