perf(spmd): don't initialise context on boot, do it on CPU_ON

Normal and Realm worlds setup their contexts whenever a core comes
online. This speeds up boot and as a side effect allows any cores that
are never turned on to not be initialised.

So do this for spmd's Secure world too. This makes all three worlds
consistent.

fix(spmd): check pwr mgmt status for SPMC framework response

The direct message response received by the SPMD upon a CPU_OFF power
management operation must be a framework message. If message indicates
SPMC denied the CPU_OFF operation, SPMD shall panic.

However, if SPMC does not support receiving power management
related framework messages from SPMD, it will return FFA_ERROR.
In such case, SPMD takes an implementation defined choice to ignore the
the FFA_ERROR and proceed with power management operation.

A structure 'spmd_spm_core_context_t' defined in 'spmd_private.h' is
also declared in 'el3_spmd_logical_sp.h' as it is used in a couple of
function declarations. These function declarations can be moved to
spmd_private.h as they are not needed elsewhere.

- Debug macros are included indirectly from assert.h. Removing

where the macros are used.
- Removing hack for fixing PLAT_LOG_LEVEL_ASSERT to 40.
Instead removing assert with expression, as this

This patch adds support for forwarding the following PSCI messages
received by the SPMC at EL3 to the S-EL1 SP if the SP has indicated
that it wishes to receive the appropriate message via its manifest.

1. A PSCI CPU_OFF message in response to a cpu hot unplug request
from the OS.
2. A message to indicate warm boot of a cpu in response to a cpu
hot plug request from the OS.
3. A PSCI CPU_SUSPEND message in response to a cpu idle event
initiated from the OS.
4. A message to indicate warm boot of a cpu from a shallow power
state in response to a cpu resume power event.

This patch also implements the FFA_SECONDARY_EP_REGISTER function to
enable the SP specify its secondary entrypoint.

feat(spmc): add FF-A secure partition manager core

This patch introduces the core support for enabling an SPMC in EL3
as per the FF-A spec.

The current implemented functionality is targeted to enable
initialization of the SPMC itself and initial support for
bringing up a single S-EL1 SP.

This includes initialization of the SPMC's internal state,
parsing of an SP's manifest, preparing the cpu contexts and
appropriate system registers for the Secure Partition.

The spmc_smc_handler is the main handler for all incoming SMCs
to the SPMC, FF-A ABI handlers and functionality will
be implemented in subsequent patches.

feat(ff-a): forward FFA_VERSION from SPMD to SPMC

Introduced by FF-A v1.1 we must forward a call to FFA_VERSION
to the SPMC so that the ffa version of the caller can be stored
for later use. Since the return of FFA_VERSION is not wrapped in
a FF-A call we need to use a direct message request to do this
forwarding. For the spmd_handler in the SPMC to hand off to the
correct function we use w2 to specify a target framework function.
Therefore we must update PSCI CPU_OFF to do this as well.
