feat(spmd): add support for FFA_EL3_INTR_HANDLE_32 ABI

When Group0 Secure interrupts in secure world get trapped to S-EL2
SPMC, FFA_EL3_INTR_HANDLE ABI is invoked by SPMC to delegate
interrupt handling to EL3 firmware (i.e., SPMD).

SPMD further delegates to platform handler which successfully handles
the Group0 secure interrupt before returning control to SPMC.

feat(spmd): introduce FFA_PARTITION_INFO_GET_REGS

Add code in SPMD to forward calls to FFA_PARTITION_INFO_GET_REGS. This
is a new ABI that allows getting partition information without the need
for rx/tx buffer, that helps in situations where having an rx/tx buffer
mapped and available is difficult (ex. uefi runtime services).
Currently, the spmc at el3 does not support this new ABI.
The new ABI uses registers x8-x17 to return partition information so
changes are made to ensure those registers are passed through to the
SPMC and restored on the return path.

feat(spmc): add support for v1.1 FF-A boot protocol

A partition can request the use of the FF-A boot protocol via
an entry in its manifest along with the register (0-3)
that should be populated with a pointer to a data structure
containing boot related information. Currently the boot
information consists of an allocated memory region
containing the SP's manifest, allowing it to map and parse
any extra information as required.

This implementation only supports the v1.1 data structures
and will return an error if a v1.0 client requests the usage
of the protocol.

feat(spmc): add support for FF-A power mgmt. messages in the EL3 SPMC

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 FFA_PARTITION_INFO_GET handler

Enable the SPMC to handle calls to FFA_PARTITION_INFO_GET.
This allows the normal world to discover which partitions
are running in the secure world including logical partitions
in EL3.

This implementation supports both the v1.0 and v1.1
implementations of the Partition Info Get Descriptor.
The SPMC populates the appropriate descriptor in the
partitions RX buffer, if requested, according to the
version of FF-A that the caller is using.

Additionally rename the common/uuid UUID_H include guard
due to a conflict with another header file.

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.
