mt8188 and mt8195 are different SoCs and we need to distinguish mt8188
from mt8195, so I think a new entry is needed for mt8188 with the
specific "compatiable".
On the other hand, mt8188 and mt8195 have same ethernet design, so the
private data "mt8195_gmac_variant" can be resued to reduce redundant
info in driver.
