feat(plat/st): improve FIP image loading from MMC

Instead of using a scratch buffer of 512 bytes, we can directly use the
image address and max size. The mmc_block_dev_spec struct info is then
overwritten for each image with this info, except FW_CONFIG and GPT
table which will still use the scratch buffer.
This allows using multiple blocks read on MMC, and so improves the boot
time.
A cache invalidate is required for the remaining data not used from the
first and last blocks read. It is not required for FW_CONFIG_ID,
as it is in scratch buffer in SYSRAM, and also because bl_mem_params
struct is overwritten in this case. This should also not be done if
the image is not found (OP-TEE extra binaries when using SP_min).

feat(plat/st): use FIP to load images

BL2 still uses the STM32 header binary format to be loaded from ROM code.
BL32 and BL33 and their respective device tree files are now put together
in a FIP file.
One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are
in charge of removing useless nodes for a given BL. This is done because
BL2 and BL32 share the same device tree files base.

The previous way of booting is still available, the compilation flag
STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files
are duplicated and their names modified with _stm32_ to avoid too much
switches in the code.

fix(plat/st): improve DDR get size function

Avoid parsing device tree every time when returning
the DDR size.
A cache flush on this size is also added because TZC400 configuration
is applied at the end of BL2 after MMU and data cache being turned off.
Configuration needs to retrieve the DDR size to generate the correct
region. Access to the size fails because the value is still in the data
cache. Flushing the size is mandatory.
