Add new support for MT7531:

MT7531 is the next generation of MT7530. 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.  

Hi Landen

Looking at the code, you seem to treat HSGMII as 2500Base-X. Is this
correct? Or is it SGMII over clocked to 2.5Gbps?

How would that work? Would 10 and 100 be overclocked to 25 and 250?
