Merge patch series "mediatek: cumulative trivial fix for OF_UPSTREAM support"

Christian Marangi <ansuelsmth@gmail.com> says:

This is an initial series that have all the initial trivial
fixes required for usage of OF_UPSTREAM for the mediatek SoC

This also contains the pcie-gen3 driver and the required tphy
support driver to make it work.

Subsequent series will follow with conversion of the mtk-clk
to permit usage of OF_UPSTREAM and upstream clk ID.

MT7981, MT7986 and MT7988 migration to upstream clock ID
is complete and working on MT7623.

Series CI tested with PR: https://github.com/u-boot/u-boot/pull/590
