[PATCH v4 0/3] MediaTek Helio X10 MT6795 - M4U/IOMMU Support

[AngeloGioacchino Del Regno]

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This series introduces support for the IOMMUs found on this SoC.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

Changes in v4:
 - Retitled mtk_iommu commits to iommu/mediatek as suggested by Yong Wu
 - Removed unused M4U_LARB5_ID definition
 - Rebased on next-20220624 and
   https://patchwork.kernel.org/project/linux-mediatek/list/?series=650969

Changes in v3:
 - Added new flag as suggested by Yong Wu
 - Rebased on top of https://patchwork.kernel.org/project/linux-mediatek/list/?series=648784

Changes in v2:
 - Rebased on top of https://patchwork.kernel.org/project/linux-mediatek/list/?series=642681
