[dts] [PATCH 1/4] framework/crb: Fixing ThunderX ethernet controler detection

[Radoslaw Biernacki <radoslaw.biernacki@linaro.org>]

Asking for link speed for ThunderX Ethernet controller is not reliable
since driver report error when the link is down. In fact we dont need
to ask for link speed as Ethernet controllers can be easily identified
by device name from lspci. The mapping will fuhrer filter out the PF
and VF interfaces which does not have the interface name assigned.

Fixes: 150716d93f5e ("framework crb: Appending only 10G devices for cavium")
