This series performs fixes the MediaTek UART DMA driver to be able
to correctly program AP_DMA controllers that support extended
addressing, performs some cleanups to improve code readability
and adds support for *all* of the SoCs generations that are upstream.

This includes MT6795, MT7988, MT8173, MT8183, MT8186, MT8188, MT8195,
other than all of their Genio variants (where applicable), all of
their Smartphone variants (where applicable), and also some newer
generation SoCs that are in the process of being upstreamed, like
MT8196 and MT8189.

Devicetrees are also already done, but not included here, and will be
sent in a different series (probably after this one gets upstreamed,
as I have to decide what to do with MT8196 - integrate it in the first
devicetree submission/commit or add it later - depends on whether this
one gets upstreamed first or not).
