[U-boot,V2,0/2] Enable mt7531 switch support for MT7629

[U-boot,V2,0/2] Enable mt7531 switch support for MT7629

[MarkLee]

This patch series enable MT7629 sgmii mode with mt7531 switch support,
	1. enable mt7629 sgmii mode support in mediatek eth driver
	2. enable mt7629 ethernet dts node with sgmii mode and mt7531
	   switch support

Change since V1:
- use driver private data from dts to decide the register offset
  (SGMSYS_GEN2_SPEED) instead of check #ifdefs in drivers.

  eth: mtk-eth: enable mt7629 sgmii mode support in mediatek eth driver
  arm: dts: mediatek: enable sgmii mode and mt7531 switch for mt7629

[U-boot, V2, 1/2] eth: mtk-eth: enable mt7629 sgmii mode support in mediatek eth driver

[MarkLee]

The sgmii mode init flow is almost the same for all mediatek SoC, the
only difference is the register offset(SGMSYS_GEN2_SPEED) is 0x2028
in the old chip(mt7622) but changed to 0x128 for the newer chip(mt7629 
and the following chips).
