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

Add a new flag for this. This setting difference is that the offset for
TF_PROT_TO_PROGRAM_ADDR is 5 in mt8173 while the others' offset is 4.
thus, we could rename the flag like TF_PORT_TO_ADDR_MT8173 or
TF_PORT_TO_ADDR_OFFSET_IS_5.
