feat(stm32mp2): manage DDR FW via FIP
This feature is enabled by default using STM32MP_DDR_FIP_IO_STORAGE.
DDR firmware binary is loaded from FIP to SRAM1 which needs to be
mapped.
Only half of the SRAM1 will be allocated to TF-A.
RISAB3 has to be configured to allow access to SRAM1.
Add image ID and update maximum number on platform side also.
Fill related descriptor information, add policy and update numbers.
DDR_TYPE variable is used to identify binary file, and image is now
added in the fiptool command line.
The DDR PHY firmware is not in TF-A repository. It can be found at
https://github.com/STMicroelectronics/stm32-ddr-phy-binary
To ease the selection of the firmware path, STM32MP_DDR_FW_PATH is added
to platform.mk file.
