MT7981 has its GMAC2 PHY shared with USB3. To enable GMAC2, mux
register must be set to connect the SGMII phy to GMAC2.

Existing SGMII support of mtk-eth is actually a MediaTek-specific
2.5Gbps high-speed SGMII (HSGMII) which does not support
auto-negotiation mode.
This patch adds SGMII 1Gbps auto-negotiation mode and rename the
existing HSGMII to 2500basex.

This patch adds support for PDMA v2 hardware. The PDMA v2 has extended the
DMA descriptor to 8-words, and some of its fields have changed comparing
to the v1 hardware.

This patch is a preparation for adding a new version of PDMA of which the
DMA descriptor fields has changed. Using bitfields will result in a complex
modification. Convert bitfields to u32 units can solve this problem easily.

Using a single soc id to control different initialization and TX/RX flow
for all SoCs is not extensible if more hardware variations are added in
the future.
This patch introduces a struct to replace the original mtk_soc to allow
the driver be able handle newer hardwares.

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).

mt7531 is a 7-ports switch with 5 embedded giga phys, and uses the same
MAC design of mt7530. The cpu port6 supports SGMII only. The cpu port5
supports RGMII or SGMII in different model.
mt7531 is connected to mt7622 via both RGMII and SGMII interfaces.
In this patch, mt7531 cpu port5 or port6 is configured to maximum
capability to align CPU MAC setting.
