The vendor kernel sets a previously unknown clock gating bit in the
VIVS_PM_MODULE_CONTROLS register to disable SH_EU clock gating.

Import new headers from rnndb for the definition and set the bit
for the VIPNano-Si+ NPU on i.MX8MP and other affected cores.

Changes in v2:
- Add patch to turn etnaviv_is_model_rev() into a function.
- Use model numbers instead of made up GCxxxx model names.
- Also disable SH_EU clock gating on other models/revisions listed in the
  vendor kernel.
- Link to v1: https://lore.kernel.org/r/20240124-etnaviv-npu-v1-0-a5aaf64aec65@pengutronix.de
