feat(imx8mp): add hab and map required memory blocks

In order for HAB to perform operations, memory regions has to be mapped
in TF-A, which HAB ROM code would use internally.

Include those memory blocks for i.MX8M+ SoC. Of a special note, the DRAM
block is mapped with complete size available on the platform and uses
MT_RW attributes, this is required to minimize the size of translation
tables and provide a possibility to exchange the execution results
between EL3 and EL1&2, see details in [1].
