chore(auth)!: remove CryptoCell-712/713 support

CryptoCell-712 and CryptoCell-713 drivers have been deprecated since
TF-A v2.9 and their removal was announced for TF-A v2.10 release.
See [1].

As the release is approaching, this patch deletes these drivers' code as
well as all references to them in the documentation and Arm platforms
code (Nuvoton platform is taken care in a subsequent patch). Associated
build options (ARM_CRYPTOCELL_INTEG and PLAT_CRYPTOCELL_BASE) have also
been removed and thus will have no effect if defined.

This is a breaking change for downstream platforms which use these
drivers.

Note that TF-A v3.0 release later got renumbered into v2.10.

build: always prefix section names with `.`

Some of our specialized sections are not prefixed with the conventional
period. The compiler uses input section names to derive certain other
section names (e.g. `.rela.text`, `.relacpu_ops`), and these can be
difficult to select in linker scripts when there is a lack of a
delimiter.

This change introduces the period prefix to all specialized section
names.

BREAKING-CHANGE: All input and output linker section names have been
prefixed with the period character, e.g. `cpu_ops` -> `.cpu_ops`.

Don't return error information from console_flush

And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

plat/arm: Make crash console functions strong

In Arm platforms the crash console doesn't print anything if the crash
happens early enough. This happens in all images, not only BL1. The
reason is that they the files ``plat/common/aarch64/platform_helpers.S``
and ``plat/arm/common/aarch64/arm_helpers.S``, and the crash console
functions are defined as weak in both files. In practice, the linker
can pick the one in ``plat/common``, which simply switches the multi
console to crash mode when it wants to initialize the crash console.
In the case of Arm platforms, there are no console drivers registered
at that point, so nothing is printed.

This patch makes the functions in plat/arm strong so that they override
the weak functions in plat/common.

plat/arm: Migrate AArch64 port to the multi console driver

The old API is deprecated and will eventually be removed.

Arm platforms now use the multi console driver for boot and runtime
consoles. However, the crash console uses the direct console API because
it doesn't need any memory access to work. This makes it more robust
during crashes.

The AArch32 port of the Trusted Firmware doesn't support this new API
yet, so it is only enabled in AArch64 builds. Because of this, the
common code must maintain compatibility with both systems. SP_MIN
doesn't have to be updated because it's only used in AArch32 builds.
The TSP is only used in AArch64, so it only needs to support the new
API without keeping support for the old one.

Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
causes the UARTs to reset (except for the one used by the TSP). This
means that they must be unregistered when suspending and re-registered
when resuming. This wasn't a problem with the old driver because it just
restarted the UART, and there were no problems associated with
registering and unregistering consoles.

The size reserved for BL2 has been increased.

Refactor Statistical Profiling Extensions implementation

Factor out SPE operations in a separate file. Use the publish
subscribe framework to drain the SPE buffers before entering secure
world. Additionally, enable SPE before entering normal world.

A side effect of this change is that the profiling buffers are now
only drained when a transition from normal world to secure world
happens. Previously they were drained also on return from secure
world, which is unnecessary as SPE is not supported in S-EL1.

ARM plat changes to enable CryptoCell integration

This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:

* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
the CryptoCell crypto driver for Trusted Board boot.

* The TrustZone filter settings for Non Secure DRAM is modified
to allow CryptoCell to read this memory. This is required to
authenticate BL33 which is loaded into the Non Secure DDR.

* The CSS platforms are modified to use coherent stacks in BL1 and BL2
when CryptoCell crypto is selected. This is because CryptoCell makes
use of DMA to transfer data and the CryptoCell SBROM library allocates
buffers on the stack during signature/hash verification.

aarch64: Enable Statistical Profiling Extensions for lower ELs

SPE is only supported in non-secure state. Accesses to SPE specific
registers from SEL1 will trap to EL3. During a world switch, before
`TTBR` is modified the SPE profiling buffers are drained. This is to
avoid a potential invalid memory access in SEL1.

SPE is architecturally specified only for AArch64.
