Having these definitions in board_arm_def.h forces to
all the arm platforms to use the same definition for
PLAT_ARM_MEM_PROT_ADDR.

This macro also enables the mem-protect mechanism,
which means that all the arm platform has enabled
mem-protect and they cannot get rid of it.

for BL1 and BL2.

Append a node to hw-config dtb which will include a property to hold
the value of the SSC_VERSION register. This will be used by the BL33
stage to determine the platform-id and the config-id of the platform
it is executing on.

Remove the existing method of populating the platform id in arg2 of
BL33 which is no longer needed with dynamic configuration feature
enabled as the BL33 will get this information directly via the config
files. Add the tb_fw_config and hw_config dts files.

The MT bit in MPIDR is always set for SGI platforms and so the
core position calculation code is updated to take into account
the thread affinity value as well.

Instead of instantiating a local copy of GICv3 driver data for SGI
platforms, reuse the existing instance of GICv3 driver data available
in the arm common platform code.

SGI-575's NSRAM is neither in the same place nor the same size as Juno's.

SGI-575 platform is based on Cortex-A75 processor which has its MT bit
in the MPIDR register set to '1'. So the Arm platform layer code has
to be made aware of this.
