SPMD: secondary cores PM on and off SPD hooks relayed to SPMC ...

Define SPMD PM hooks for warm boot and off events. svc_on_finish handler
enters the SPMC at the entry point defined by the secondary EP register
service. The svc_off handler notifies the SPMC that a physical core is
being turned off through a notification message.

SPMD: handle SPMC message to register secondary core entry point ...

Upon booting, the SPMC running on the primary core shall register the
secondary core entry points to which a given secondary core being woken
up shall jump to into the SPMC . The current implementation assumes the
SPMC calls a registering service implemented in the SPMD for each core
identified by its MPIDR. This can typically happen in a simple loop
implemented in the early SPMC initialization routines by passing each
core identifier associated with an entry point address and context
information.
This service is implemented on top of a more generic SPMC<=>SPMD
interface using direct request/response message passing as defined by
the FF-A specification.

libc/memset: Implement function in assembler ...

Trace analysis of FVP_Base_AEMv8A model running in
Aarch32 mode with the build options listed below:
TRUSTED_BOARD_BOOT=1 GENERATE_COT=1
ARM_ROTPK_LOCATION=devel_ecdsa KEY_ALG=ecdsa
ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_ecdsa.pem
shows that when auth_signature() gets called
71.84% of CPU execution time is spent in memset() function
written in C using single byte write operations,
see lib\libc\memset.c.
This patch replaces C memset() implementation with assembler
version giving the following results:
- for Aarch32 in auth_signature() call memset() CPU time
reduced to 24.84%.
- Number of CPU instructions executed during TF-A
boot stage before start of BL33 in RELEASE builds:
----------------------------------------------
|  Arch   |     C      |  assembler |    %   |
----------------------------------------------
| Aarch32 | 2073275460 | 1487400003 | -28.25 |
| Aarch64 | 2056807158 | 1244898303 | -39.47 |
----------------------------------------------
The patch also replaces memset.c with aarch64/memset.S
in plat\nvidia\tegra\platform.mk.
