Merge branch 'fec-new-type-device'

Andy Duan says:

====================
net: fec: add new type device

Different i.MX SOC FEC support different features like :
    - i.MX6Q/DL FEC does not support AVB and interrupt coalesc
    - i.MX6SX/i.MX7D supports AVB and interrupt coalesc
    - i.MX6UL/ULL does not support AVB, but support interrupt coalesc

Then, add new quirk flag to judge the supported features, and add new
type device for i.MX6UL.
