clk: stm32mp: enable RTCAPB clock for dual-core chips ...

In order to correctly manage the bring-up of non boot CPUs, the RTCAPB
clock needs to be enabled.
It controls the access to backup registers, where the CPU entrypoint
will be stored.

stm32mp1: add watchdog support ...

Introduce driver for STM32 IWDG peripheral (Independent Watchdog).
It is configured according to device tree content and should be enabled
from there.
The watchdog is not started by default. It can be started after an HW
reset if the dedicated OTP is fused.

The watchdog also needs to be frozen if a debugger is attached.
This is done by configuring the correct bits in DBGMCU.
This configuration is allowed by checking BSEC properties.

An increase of BL2 size is also required when adding this new code.

console: add a flag to prepend '\r' in the multi-console framework ...

Currently, console drivers prepend '\r' to '\n' by themselves. This is
common enough to be supported in the framework.

Add a new flag, CONSOLE_FLAG_TRANSLATE_CRLF. A driver can set this
flag to ask the framework to transform LF into CRLF instead of doing
it by itself.

Switch AARCH32/AARCH64 to __aarch64__ ...

NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.

All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)

Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ ...

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

cryptocell: move Cryptocell specific API into driver ...

Code using Cryptocell specific APIs was used as part of the
arm common board ROT support, instead of being abstracted
in Cryptocell specific driver code, creating two problems:
- Any none arm board that uses Cryptocell wuld need to
  copy and paste the same code.
- Inability to cleanly support multiple versions of Cryptocell
  API and products.

Move over Cryptocell specific API calls into the Cryptocell
driver, creating abstraction API where needed.
