Support 32bit descriptor MMU table. This is required by ARMv7
architectures that do not support the Large Page Address Extensions.

nonlpae_tables.c source file is dumped from the OP-TEE project:
core_mmu_armv7.c and related header files.

This patch adds support for Versatile express FVP (Fast models).
Versatile express is a family of platforms that are based on ARM v7.
Currently this port has only been tested on Cortex A7, although it
should work with other ARM V7 cores that support LPAE, generic timers,
VFP and hardware divide. Future patches will support other
cores like Cortex A5 that dont support features like LPAE
and hardware divide. This platform is tested on and only expected to
work on single core models.

fvp: trusty: Move dynamic xlat enable to platform

SPM: Remove unnecessary register save

Series of new patches for STM32MP1

docs: Update note about plat/arm in Porting Guide

Since commit 01fc1c24

 ("BL31: Use helper function to save registers
in SMC handler") all the general-purpose registers are saved when
entering EL3. It isn't needed to save them here.

Regulator configuration at boot takes more information from DT.
I2C configuration from DT is done in I2C driver.
I2C driver manages more transfer modes.
The min voltage of buck1 should also be increased to 1.2V,
else the platform does not boot.

Heavily modifies stm32_i2c.c since many functions move inside the source
file to remove redundant declarations.

timeout_init_us(some_timeout_us); returns a reference to detect
timeout for the provided microsecond delay value from current time.

timeout_elapsed(reference) return true/false whether the reference
timeout is elapsed.

This change is inspired by the OP-TEE OS timeout resources [1].

MMU initializes, thus the scrubbing is moved to ddr intialization phase.

Rather than letting the Trusty makefile set the option to enable dynamic
translation tables, make platforms do it themselves.

This also allows platforms to replace the implementation of the
translation tables library as long as they use the same function
prototypes.

Now that we have non-blocking TI-SCI functions we can initiate the shutdown
sequence from the PSCI handler without needing the ti_sci_proc_shutdown

Most TI-SCI functions request an ACK and wait until it is received. For
some power sequence tasks we cannot wait but instead queue messages
asynchronously. Three messages have been identified that will need to
