Introduce new driver for modern Exynos ARMv8 SoCs, e.g. Exynos850. Also
it's used for Google's GS101 SoC.
This is squashed commit, contains next patches of different authors. See
`iommu-exynos850-dev' branch for details: [1].
Original authors (Samsung):
- Cho KyongHo
- Hyesoo Yu

This is a draft of a new IOMMU driver used in modern Exynos SoCs (like
Exynos850) and Google's GS101 SoC (used in Pixel 6 phone). Most of its
code were taken from GS101 downstream kernel [1], with some extra
patches on top (fixes from Exynos850 downstream kernel and some porting
changes to adapt
Only example of usage and header for now.

Hello,
syzbot found the following issue on:
HEAD commit:e3a8b6a1e70c Merge tag 'slab-for-5.17-part2' of git://git...
git tree: upstream
console output: https://syzkaller.appspot.com/x/log.txt?x=1507e01fb0
kernel config: https://syzkaller.appspot.com/x/.config?x=73c17fd2d4a060fe
This means the DMA API is called on a not DMA capable device. This
needs fixing in the caller.
