refactor(docs): convert PSCI performance data into csv-tables

Browse Source 
The PSCI instrumentation data in docs is carefully formatted by a script
on each release. However, to produce these tables it is necessary to
keep the raw data out of tree to run the script against to produce the
table. Then, it's necessary to manually edit the docs source code to
interleave this with headings. Overall this takes a while and is not
particularly engaging to do.

Instead, store the raw data in a CSV file alongside docs. Then, the RST
format conveniently has the `csv-table` directive which allows this to
be rendered automatically. The job of updating becomes much simpler -
just replace the data.

This patch also sets some formatting of the RST tables so that they look
aligned.

Given that runtime instrumentation using PMF is invasive, there is a small
(unquantified) overhead on the results. PMF uses the generic counter for
timestamps, which runs at 50MHz on Juno.
The following source trees and binaries were used:
- `TF-A v2.14-rc0`_
- `TFTF v2.14-rc0`_
timestamps, which runs at 50MHz on Juno. Testing was done after the rc0 tag.

=======================================
For this test we used the N1 System Development Platform (`N1SDP`_), which
contains an SoC consisting of two dual-core Arm N1 clusters.
The following source trees were used:
- `TF-A v2.14-rc0`_
- `TFTF v2.14-rc0`_
contains an SoC consisting of two dual-core Arm N1 clusters. Testing was done
after the rc0 tag.
Please see the Runtime Instrumentation :ref:`Testing Methodology
