plat: marvell: armada: a8k: change CCU LLC SRAM mapping

Browse source 
The LLC SRAM will be enabled in OP-TEE OS for usage as secure storage.
The CCU have to prepare SRAM window, but point to the DRAM-0 target
until the SRAM is actually enabled.
This patch changes CCU SRAM window target to DRAM-0
Remove dependence between LLC_SRAM and LLC_ENABLE and update the
build documentation.
The SRAМ base moved to follow the OP-TEE SHMEM area (0x05400000)

@ -79,10 +79,12 @@ There are several build options:
- LLC_SRAM
Flag defining the LLC (L3) cache SRAM support. The feature is
disabled by default (``LLC_ENABLE=0``).
When LLC SRAM is enabled, the secure payload (BL32) is loaded into this
SRAM area instead of the DRAM.
Flag enabling the LLC (L3) cache SRAM support. The LLC SRAM is activated and used
by Trusted OS (OP-TEE OS, BL32). The TF-A only prepares CCU address translation windows
for SRAM address range at BL31 execution stage with window target set to DRAM-0.
When Trusted OS activates LLC SRAM, the CCU window target is changed to SRAM.
There is no reason to enable this feature if OP-TEE OS built with CFG_WITH_PAGER=n.
Only set LLC_SRAM=1 if OP-TEE OS is built with CFG_WITH_PAGER=y.
