Distros (e.g. Buildroot and Android) can have different secure partition
layout.
This commit iterates the DPE metadata table and finds index (i) for the
first entry of the secure partition, connecting with the defined secure
partition number NUM_SP, so the last secure partition index is:
i + NUM_SP - 1
Instead of setting the certificate in hard code, dynamically enables the
certificate for the last secure partition base on calculated index.

The previous code used 64-bit registers as the target and source for
load and store operations on 32-bit hardware registers. In certain
cases (e.g., when using USART1 as the debug console), this could result
in deadlocks where the A35 gets stuck in a permanent loop due to test
conditions that are never fulfilled.
To resolve this issue, 32-bit registers are now used for these
operations.

- VCORE DVFS is the feature to change VCORE/DDR Freq for power saving
- When there are no requests for using Vcore/DRAM, Vcore DVFS will
- lower the voltage and frequency of Vcore/DRAM to achieve power saving.

Ref: https://linaro.atlassian.net/browse/TFC-669
The initial LTS document was created as pdf and was maintained in a
shared folder location, to avoid pdf getting lost and trying to find
where it is we decided to have LTS details part of docs in TF-A.
This patch directly reflects the data from pdf attached to TFC-669.
Any improvements or amends to this will be done at later phases based
on LTS maintainers comments and agreements.

timer ops structure. Fix it by moving generic delay timer init
prior to console setup to make sure that time is setup before DCC
console setup.
