SYSRAM is only 128KB and starts at 0x2FFE0000.
SRAMs are added.
BL2 code and DTB sizes are also reduced to fit in 128KB.

Because the BL2 is not relocated, the usage of BL2_IN_XIP_MEM
can be used. It reduces the binary size by removing all relocation
sections. XIP will not be used when STM32MP_USE_STM32IMAGE is
defined. Introduce new definitions for SEPARATE_CODE_AND_RODATA.

Add required code to support FCONF on STM32MP1 platform.
The new FW_CONFIG DT file will be inside the FIP, and loaded by BL2.
It will be used to configure the addresses where to load other binaries.
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.

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.
