BL2 should be agnostic of which BL32 is in the FIP (OP-TEE or SP_min),
so optee_utils.c is always compiled, and some OP-TEE flags are removed.

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).

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.

Protect BL32 (SP_min) with MMU if OP-TEE is not used.
Validate OP-TEE header with optee_header_is_valid().
Use default values in bl2_mem_params_descs[]. They will be overwritten
in bl2_plat_handle_post_image_load() if OP-TEE is used.

Now that the DDR is mapped secured, the security settings (TZC400
firewall) have to be applied at the end of BL2 for the OP-TEE case.
This is required to avoid checskum computation error on U-Boot binary,
for which MMU and TZC400 would not be aligned.

Some parameters from BootROM boot context can be required after boot.
To save space in SYSRAM, this context can be overwritten during images
load sequence. The needed information (here the boot interface) is
then saved in a local variable.

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.

In BL2, the DDR can be mapped as secured in MMU, as no other SW
has access to it during its execution.
The TZC400 configuration is also updated to reflect this. When using
OP-TEE, the TZC400 is reconfigured at the end of BL2, to match OP-TEE
mapping. Else, SP_min will be in charge to reconfigure TZC400 to set
DDR non-secure.

BSEC services should return SMC error codes as other IDs (defined in
stm32mp1_smc.h) and not BSEC driver ones. So that non-secure caller
is able to treat them correctly.
In global SMC handler, unknown ID should also return a value from this
definition list, and not the generic one, which seems not well adapted
for our needs.
Two unsigned values initializations are also changed from 0 to 0U.
