Subject: [PATCH v4] net: ethernet: faraday: To support device tree usage.

We also use the same binding document to describe the same faraday ethernet
controller and add faraday to vendor-prefixes.txt.

Signed-off-by: Greentime Hu <green.hu@...il.com>

Changes in v4:
  - Use the same binding document to describe the same faraday ethernet controller and add faraday to vendor-prefixes.txt.
Changes in v3:
  - Nothing changed in this patch but I have committed andestech to vendor-prefixes.txt.
Changes in v2:
  - Change atmac100_of_ids to ftmac100_of_ids
