As done recently for plat/tc0 in b5863cab

, enable AMU explicitly.
This is necessary as the recent changes that enable SVE for the secure
world disable AMU by default in the CPTR_EL3 reset value.

This commit enables trusted-firmware-a with Trusted Board Boot support
for the Diphda 64-bit platform.

Diphda uses a FIP image located in the flash. The FIP contains the
following components:

- BL2
- BL31
- BL32
- BL32 SPMC manifest
- BL33
- The TBB certificates

The board boot relies on CoT (chain of trust). The trusted-firmware-a
BL2 is extracted from the FIP and verified by the Secure Enclave
processor. BL2 verification relies on the signature area at the
beginning of the BL2 image. This area is needed by the SecureEnclave
bootloader.

Then, the application processor is released from reset and starts by
executing BL2.

BL2 performs the actions described in the trusted-firmware-a TBB design
document.

We don't ever expect to load a binary with an STM32 header on the Arm
FVP platform so remove this type of image from the list of
measurements.

Also remove the GPT image type from the list, as it does not get
measured. GPT is a container, just like FIP is. We don't measure the FIP
but rather the images inside it. It would seem logical to treat GPT the
same way.

Besides, only images that get loaded through load_auth_image() get
measured right now. GPT processing happens before that and is handled in
a different way (see partition_init()).

NOTE: Breaking change to the way UUIDs are stored in the DT

Currently, UUIDs are stored in the device tree as
sequences of 4 integers. There is a mismatch in endianness
between the way UUIDs are represented in memory and the way
they are parsed from the device tree. As a result, we must either
store the UUIDs in little-endian format in the DT (which means
that they do not match up with their string representations)
or perform endianness conversion after parsing them.

Currently, TF-A chooses the second option, with unwieldy
endianness-conversion taking place after reading a UUID.

To fix this problem, and to make it convenient to copy and
paste UUIDs from other tools, change to store UUIDs in string
format, using a new wrapper function to parse them from the
device tree.

A Neoverse reference design platform can have two or more variants that
differ in core count, cluster count or other peripherals. To allow reuse
of platform code across all the variants of a platform, introduce build
option CSS_SGI_PLATFORM_VARIANT for Arm Neoverse reference design
platforms. The range of allowed values for the build option is platform
specific. The recommended range is an interval of non negative integers.

An example usage of the build option is
make PLAT=rdn2 CSS_SGI_PLATFORM_VARIANT=1

To make it possible to use the hw_config device tree for dynamic
configuration in BL31 on the Arm Juno platform. A placeholder hw_config
has been added that is included in the FIP and a Juno specific BL31
setup has been added to populate fconf with the hw_config.

Juno's BL2 setup has been updated to align it with the new behavior
implemented in the Arm FVP platform, where fw_config is passed in arg1
to BL31 instead of soc_fw_config. The BL31 setup is expected to use the
fw_config passed in arg1 to find the hw_config.
