board: st: stm32mp15: support dynamic A/B bank bootup
Following commit 4300f9f4c5d7 ("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
