plat: marvell: armada: platform definitions cleanup

- Remove
    TRUSTED_DRAM_BASE
    TRUSTED_DRAM_SIZE
    MARVELL_TRUSTED_SRAM_BASE
- Rename
    PLAT_MARVELL_TRUSTED_DRAM_* -> PLAT_MARVELL_TRUSTED_RAM_*
    PLAT_MARVELL_TRUSTED_SRAM_* -> MARVELL_TRUSTED_DRAM_*
    MARVELL_MAP_SHARED_RAM -> MARVELL_MAP_SECURE_RAM
- Move
    MARVELL_TRUSTED_DRAM_SIZE to marvell_def.h
- Enable MARVELL_MAP_SECURE_RAM region in BL2U memory map
- Add dependency of MARVELL_MAP_SHARED_RAM on LLC_SRAM
- Add minor style improvents
