[PATCH v2 0/3] SM8450 IPA support

[Esteban Urrutia <esteuwu@proton.me>]

This series has been tested on the following SoCs:
- SM7475
- SM8450
- SM8475
In these the modem works as expected and no crashes occur.

Changes in v2:
- Add missing resource limits for DMA and QDSS source groups.
  - These are marked as unused downstream, but still have values written
  to them.
- Add Nazar as a co-developer.
  - We developed independent implementations and are both working on
  this series.
- Add the IPA_MEM_MODEM_STATS_DROP memory region.
- Pick tags.
- Rebase against linux-next.
- Remove comment in driver stating smem_size differences.
  For both SM8450 and SM8475 SoCs:
  - All devices based on these SoCs use an smem_size of 0x9000. [1]
  - Specifying an smem_size of 0xb000 causes the modem to assert a
  shared memory allocation failure. [2]
- Remove overlapping optional memory regions.
  - No comments from anyone regarding these, so remove them.
- Reorder patches. (Dmitry, Krzysztof)
- Sort iommus property in DT. (Krzysztof)
- Specify actual IMEM base and size in DT. (Konrad)
- Update commit messages and cover letter.
- Link to v1: https://patch.msgid.link/20260622-sm8450-ipa-v1-0-532f0299f96e@proton.me
