Enable GPI DMA on SM6125 by using the new sdm845 compatible with
ee_offset 0.
Changes since v1:
- Drop driver patch in favour of using generic qcom,sdm845-gpi-dma
compatible [1];
- Replace status = "okay" with "disabled";
- Use 3 instead of 5 dma cells;
- Reorder properties;
- Explicitly depend on APPS SMMU series to have apps_smmu label available.
v1: https://lore.kernel.org/all/20221001185526.494095-1-martin.botka@somainline.org/T/#u
Depends on:
- SM6125 APPS SMMU: https://lore.kernel.org/linux-arm-msm/20221216215819.1164973-1-marijn.suijten@somainline.org/T/#u

The stream id does not need the leading zero.
You made the mask a decimal zero in the previous patchset, please
decide on one convention. Masks are generally more useful as hex,
but for zero values I suppose zero is less noise for the same thing..
The DMA nodes however, look good otherwise.

Good catch! Will clean this up for V2.

The _vast majority_ of qcom dts uses 0x0, I'll fix that in the previous
patch series. Looks like I did even clean that up when directly
transplanting that patch ("Add apps_smmu with streamID to SDHCI 1/2
nodes") to sm6350 even...

And they work great, too!
