On systems that have multiple platform components that can interpret the
SCMI messages, there is a need to support multiple SCMI channels (one
each to those platform components). Extend the existing SCMI interface
that currently supports only a single SCMI channel to support multiple
SCMI channels.

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link, for now only dual-chip
is supported.
Whether or not multiple chips are present is dynamically probed by
SCP firmware and passed on to TF-A, routing table will be set up
only if multiple chips are present.
Initialize GIC-600 multichip operation by overriding the default GICR
frames with array of GICR frames and setting the chip 0 as routing
table owner.

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link for now only dual-chip is
supported.
A single instance of TF-A runs on master chip which should be aware of
slave chip's CPU and memory topology.
This patch updates platform macros to include remote chip's information
and also ensures that a single version of firmware works for both single
and dual-chip setup.

Platform information structure holds information about platform's DDR
size(local/remote) which will be used to zero out the memory before
enabling the ECC capability as well as information about multichip
setup. Multichip and remote DDR information can only be probed in SCP,
SDS region will be used by TF-A to get this information at boot up.
This patch introduces a new SDS to store platform information, which is
populated dynamically by SCP Firmware.previously used mem_info SDS is
also made part of this structure itself.
The platform information is also passed to BL33 by copying it to Non-
Secure SRAM.

The DMC-620 memory controllers in N1SDP platform has to be put
into CONFIG state before writing to ERR0CTLR0 register to enable
ECC.
This patch fixes the sequence so that DMCs are set to CONFIG
state before writing to ERR0CTLR0 register and moved back to
READY state after writing.

N1SDP platform supports RDIMMs with ECC capability. To use the ECC
capability, the entire DDR memory space has to be zeroed out before
enabling the ECC bits in DMC620. Zeroing out several gigabytes of
memory from SCP is quite time consuming so functions are added that
zeros out the DDR memory from application processor which is
much faster compared to SCP. BL33 binary cannot be copied to DDR memory
before enabling ECC so this is also done by TF-A from IOFPGA-DDR3
memory to main DDR4 memory after ECC is enabled.
Original PLAT_PHY_ADDR_SPACE_SIZE was limited to 36-bits with which
the entire DDR space cannot be accessed as DRAM2 starts in base
0x8080000000. So these macros are redefined for all ARM platforms.

Use full include paths like it is done for common includes.
This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

In order to allow Arm platforms to override the default list of PSCI
callbacks, remove the existing weak implementation of
'plat_arm_psci_override_pm_ops' function and let all the Arm platforms
implement their own 'plat_arm_psci_override_pm_ops' function.
For platforms that support SCMI protocol, the function
'css_scmi_override_pm_ops' can be additionally used as well to
override the default PSCI callbacks.

This patch adds support for the N1SDP (NeoVerse N1 System Development
Platform). It is an initial port and additional features are expected
to be added later.
The port includes only BL31 support as the System Control Processor
(SCP) is expected to take the role of primary boatloader
