Subject: [PATCH v2 0/3] arm64: dts: qcom: sm6125: QUPs, SPI and Seine I2C buses

Introduce Qualcomm Universal Peripheral support on SM6125 and define all
known SPI and I2C Serial Engines.  On Sony Seine PDX201 all I2C buses
with known-connected hardware are enabled for future hardware mapping,
together with the respective GPI DMA 0 and QUP 0.

Changes since v1:
- Un-downstream pinctrl mapping:
  - Remove nested mux {} / config {};
  - Remove useless comments;
  - Remove unreferenced pinctrl states;
- Use qup14 pinctrl function name instead of unknown qup_14;
- Reword commit message;
- Add iommus to QUP nodes now that this series depends on apps_smmu to
  be available;
- Reorder all properties to match other SoCs;
- Reorder/intersperse QUP nodes with GPI DMA nodes to maintain sorting
  by address;
- Reorder SPI nodes to fit in with I2C nodes, restoring sorting by
  address too;
- Use QCOM_GPI_* constants;
- Adhere to 3 instead of 5 dma cells for gpi_dma.

v1: https://lore.kernel.org/all/20221001185628.494884-1-martin.botka@somainline.org/T/#u
