A collection of device tree fixes and additions for the i.MX 8ULP SoC
and its EVK boards:

SoC-level (imx8ulp.dtsi):
- Add DMA channel properties to LPI2C, LPUART and LPSPI nodes and
  replace hardcoded eDMA direction flags with FSL_EDMA_RX /
  FSL_EDMA_MULTI_FIFO macros for SAI and SPDIF nodes.
- Add the I3C2 controller node (Silvaco IP).
- Correct the SRAM node base address and size to cover the full 64 KB
  SSRAM P2 partition instead of only the last 4 KB.
- Add assigned-clock properties to LPUART4-7 so the clock framework
  configures the input clock automatically during probe.

Board-level (imx8ulp-evk.dts):
- Add a gpio-keys node for the power-on button (PTF31).
- Enable LPUART6 with flow control for NXP 88W8987 Bluetooth.
- Enable LPUART7 for the FT4232 PortD serial on proto1B boards.
- Reduce ENET pad drive strength and slew rate on PTE14-17/22/23 to
  fix signal overshoot.

Board-level (imx8ulp-9x9-evk.dts):
- Rename the model string from "EVK9" to "9x9 EVK" to follow the
  i.MX die-size naming convention.
