Dario Binacchi 560d8f3270 board: st: stm32mp15: support dynamic A/B bank bootup
Following commit 4300f9f4c5 ("board: st: stm32mp25: support dynamic
A/B bank bootup"), this patch enables automatic detection of the active
A/B bank on STM32MP15 platforms by retrieving partition GUIDs from FWU
metadata.

This ensures the system correctly identifies the bootable partitions
even in multi-bank scenarios, falling back to a standard bootable flag
scan if the UUIDs are missing.

To enable A/B bank bootup on STM32MP15 boards, add the following Kconfig
options to the  stm32mp15[_basic]_defconfig:

 CONFIG_FWU_MULTI_BANK_UPDATE=y
 CONFIG_FWU_MDATA=y
 CONFIG_FWU_NUM_BANKS=2
 CONFIG_FWU_NUM_IMAGES_PER_BANK=3
 CONFIG_CMD_FWU_METADATA=y
 CONFIG_FWU_MDATA_V2=y
