[S.H] 'compatible' and 'phy-mode' are standard properties already in common Ethernet
phy binding, I can update 'phy-mode' with "1000base-kx" and "10gbase-kr", how
about I still list the two properties here for the requirement of PCS PHY to support
backplane?

[S.H] OK. will add fsl prefix.

Thank you for reviewing the patch!
