refactor(plat/st): map DDR secure at boot

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.
