doc: Update links within imported wiki content ...

This patch covers two changes:

- Links that refer to GitHub are updated to point to the
  relevant content on trustedfirmware.org

- Internal links between documents have been updated,
  with the required .rst suffix being added or due
  to a change in the relative locations of the files.

doc: Migrate a subset of the GitHub wiki content ...

With the TF wiki being migrated from GitHub to trustedfirmware.org,
some documents will be moved into the docs/ directory within the
repository rather than remaining as external content. The
appropriate action has been decided on a per-document basis.

BL31: Enable pointer authentication support in warm boot path ...

In the current Pointer Authentication support added in
commit b86048c
PAuth gets enabled in BL31 cold boot entrypoint only,
(see bl31_entrypoint() in bl31\aarch64\bl31_entrypoint.S)
but not in bl31_warm_entrypoint().
This results in EnIA bit [31] in SCTLR_EL3 not being set
and pointer authentication disabled after CPU wake-up event.

stm32mp1: zeromem device_info struct ...

The change of the structure highlighted the fact that all fields are not
correctly initialized with zeroes.

Replace the other memset in the function with zeromem, as it is faster.

drivers: mmc: Fix some issues with MMC stack ...

Some bugs in MMC stack needs to be fixed:
- scr cannot be local as this will cause cache issue when invalidating
after the read DMA transfer is completed
- ACMD41 needs to send voltage information in initialization, otherwise the
command is a query, thus will not initialize the controller
- when checking device state, retry until the retries counter goes to zero
before failing

We should be using zeromem to scrub memory instead of memset. This would

xlat_tables_v2: print xlat tables without recursion ...

This patch uses an array on stack to save parent xlat table information when
traversing the xlat tables. It keeps exactly same xlat table traversal
order compared to recursive version.

Tegra: dummy support for the io_storage backend ...

This patch provides dummy macros and platform files to compile
the io_storage driver backend. This patch is necessary to
remove the "--unresolved=el3_panic" linker flag from Tegra's
makefiles and allow us to revert this workaround, previously
suggested by the ARM toolchain team.

The "--unresolved=el3_panic" flag actually was a big hammer that
allowed Tegra platforms to work with armlink previously but it
masks legit errors with the code as well.
