This patch series adds support for MT7531.

MT7531 is the next generation of MT7530 which could be found on Mediatek
router platforms such as MT7622 or MT7629. 

It is also a 7-ports switch with 5 giga embedded phys, 2 cpu ports, and
the same MAC logic of MT7530. Cpu port 6 only supports HSGMII interface.
Cpu port 5 supports either RGMII or HSGMII in different HW SKU. Due to
support for HSGMII interface, pll, and pad setting are different from
MT7530.

Hi

thank you for the DSA-driver, works so far, but a bit to improve:

i got some retransmitts on RX (TX looks good)...i guess a clk/pll problem
