This patch set introduces DeviceTree support for the NXP FRDM-IMX91S
development board based on the i.MX91 SoC. FRDM-IMX91S is a cost-optimized
variant of FRDM-IMX91 and differs in several hardware aspects:

- 512MB LPDDR4 (FRDM-IMX91 uses 1GB)
- 256MB FlexSPI-NAND (FRDM-IMX91 uses 8GB eMMC)
- Single GbE port (FRDM-IMX91 has dual GbE)
- PMIC PF9453 (FRDM-IMX91 uses PCA9451A)

This patch has been tested on FRDM-IMX91S board and verified for basic
functionality.
