SPM: Register Secure Partition priority level with ehf module

Register a priority level, PLAT_SP_PRI, for secure partition with EL3
exception handling framework(ehf) module.

The secure partition manager(SPM) would raise the core's priority to
PLAT_SP_PRI before entering the secure partition, to protect the core
from getting interrupted while in secure partition.

Standardise header guards across codebase

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

plat/arm/sgi: disable Ares cpu power down bit in reset handler

On SGI platforms that include Ares CPUs, the 'CORE_PWRDN_EN' bit of
'CPUPWRCTLR_EL1' register requires an explicit write to clear it to
enable hotplug and idle to function correctly.

The reset value of the CORE_PWRDN_EN bit is zero but it still requires
this explicit clear to zero. This indicates that this could be a model
related issue but for now this issue can be fixed be clearing the
CORE_PWRDN_EN bit in the platform specific reset handler function.

The default values of 'plat_css_scmi_plat_info' is not applicable for
all the platforms. There should be a provision to let platform code to
register a platform specific instance of scmi_channel_plat_info_t.

Add a new API 'plat_css_get_scmi_info' which lets the platform to
register a platform specific instance of scmi_channel_plat_info_t and
remove the default values.

In addition to this, the existing 'plat_css_scmi_plat_info' structure
is removed from the common code and instantiated for the platforms that
need it. This allows for a consistent provisioning of the SCMI channel
information across all the existing and upcoming platforms.

Dynamically populating the 'system-id' node in the HW_CONFIG dts makes
it difficult to enforce memory overlap checks. So add the system-id node
in the HW_CONFIG dts file as a place holder with 'platform-id' and
'config-id' set to zero.

The code at BL2 stage determines the values of 'platform-id' and
'config-id' at runtime and updates the corresponding fields in the
system-id node of HW_CONFIG dts.

plat/arm: Remove file arm_board_def.h

This file is shared between FVP and all CSS platforms. While it may be
true that some definitions can be common, it doesn't make sense
conceptually. For example, the stack size depends on the platform and so
does the SRAM size.

After removing them, there are not enough common definitions to justify
having this header, so the other definitions have been moved to the
platform_def.h of FVP, board_css_def.h and arm_def.h.

plat/arm: Remove option ARM_BOARD_OPTIMISE_MEM

This option makes it hard to optimize the memory definitions of all Arm
platforms because any change in the common defines must work in all of
them. The best thing to do is to remove it and move the definition to
each platform's header.

FVP, SGI and SGM were using the definitions in board_arm_def.h. The
definitions have been copied to each platform's platform_def.h. Juno
was already using the ones in platform_def.h, so there have been no
changes.
