It's always nice to see a new SoC family.

Given how closely related this probably is to MT7623/MT7622, should this
perhaps just be part of arch/arm/mach-mediatek? According to
https://wikidevi.wi-cat.ru/MediaTek#xPON, the older (mips based) MT752x
chips are apparently just rebranded to EN752x after the business unit
was spun off, but I guess they are still in the same family.

Why is this needed?
Note also the comment directly above it exlaining
