Abdellatif El Khlifi 7f70cd2923 feat: disabling non volatile counters in diphda
At this stage of development Non Volatile counters are not implemented
in the Diphda platform.

This commit disables their use during the Trusted Board Boot by
overriding the NV counters get/set functions.

Abdellatif El Khlifi bf3ce99371 feat: adding the diphda platform
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.
