The STM32MP13 default environment only handles MMC and serial/USB boot.
When TF-A reports BOOT_FLASH_SPINAND the boot_device variable is set to
'spi-nand' but bootcmd_stm32mp never redirects boot_targets to ubifs0,
so distro_bootcmd falls through to MMC/USB.
This change mirrors the STM32MP15 logic:
- Add a BOOT_TARGET_UBIFS entry to BOOT_TARGET_DEVICES so that
bootcmd_ubifs0 is defined (ubi part UBI; ubifsmount ubi0:boot).
- Add the 'spi-nand' / 'nand' clause to bootcmd_stm32mp so that
boot_targets is set to 'ubifs0' when booting from NAND.
