net: ethernet: mtk_eth_soc: add version in mtk_soc_data

Introduce version field in mtk_soc_data data structure in order to
make mtk_eth driver easier to maintain for chipset configuration
codebase. Get rid of MTK_NETSYS_V2 bit in chip capabilities.
This is a preliminary patch to introduce support for MT7988 SoC.
