[U-Boot] [RFC PATCH v1 1/7] net: mvgbe: fallback phy-mode to GMII

[Chris Packham <judge.packham@gmail.com>]

Some existing device trees don't specify a phy-mode so fallback to GMII
when a phy-mode is not provided.

This is similar to what the Linux mv643xx_eth.c network driver does to
handle the same case.
