Move the FVP power driver to a directory under the FVP platform
port as this is not a generically usable driver.

Move almost all system include files to a logical sub-directory
under ./include. The only remaining system include directories
not under ./include are specific to the platform. Move the
corresponding source files to match the include directory
structure.
Also remove pm.h as it is no longer used.

- Use the TrustZone controller on Base FVP to program DRAM access
permissions. By default no access to DRAM is allowed if
'secure memory' is enabled on the Base FVP.
- The Foundation FVP does not have a TrustZone controller but instead
has fixed access permissions.
- Update FDTs for Linux to use timers at the correct security level.
- Starting the FVPs with 'secure memory' disabled is also supported.
Limitations:
Virtio currently uses a reserved NSAID. This will be corrected in
future FVP releases.

The BL images share common stack management code which provides
one coherent and one cacheable stack for every CPU. BL1 and BL2
just execute on the primary CPU during boot and do not require
the additional CPU stacks. This patch provides separate stack
support code for UP and MP images, substantially reducing the
RAM usage for BL1 and BL2 for the FVP platform.
This patch also provides macros for declaring stacks and
calculating stack base addresses to improve consistency where
this has to be done in the firmware.
The stack allocation source files are now included via
platform.mk rather than the common BLx makefiles. This allows
each platform to select the appropriate MP/UP stack support
for each BL image.
Each platform makefile must be updated when including this
commit.

Rename drivers/console/console.c to
drivers/arm/peripherals/pl011/pl011_console.c. This makes it clear
that this is a pl011 specific console implementation.

This commit isolates the accessor functions in pl011.c and builds
a wrapper layer for console functions.
This also modifies the console driver to use the pl011 FIFO.

This change requires all platforms to now specify a list of source files
rather than object files.
New source files should preferably be specified by using the path as
well and we should add this in the future for all files so we can remove
use of vpath. This is desirable because vpath hides issues like the fact
that BL2 currently pulls in a BL1 file bl1/aarch64/early_exceptions.S
and if in the future we added bl2/aarch64/early_exceptions.S then it's
likely only one of the two version would be used for both bootloaders.
This change also removes the 'dump' build target and simply gets
bootloaders to always generate a dump file. At the same time the -x
option is added so the section headers and symbols table are listed.

This patch factors out the ARM FVP specific code to create MMU
translation tables so that it is possible for a boot loader stage to
create a different set of tables instead of using the default ones.
The default translation tables are created with the assumption that
the calling boot loader stage executes out of secure SRAM. This might
not be true for the BL3_2 stage in the future.
A boot loader stage can define the `fill_xlation_tables()` function as
per its requirements. It returns a reference to the level 1
translation table which is used by the common platform code to setup
the TTBR_EL3.
This patch is a temporary solution before a larger rework of
translation table creation logic is introduced.

The Firmware Image Package (FIP) driver allows for data to be loaded
from a FIP on platform storage. The FVP supports loading bootloader
images from a FIP located in NOR FLASH.
The implemented FVP policy states that bootloader images will be
loaded from a FIP in NOR FLASH if available and fall back to loading
individual images from semi-hosting.
NOTE:
- BL3-3(e.g. UEFI) is loaded into DRAM and needs to be configured
to run from the BL33_BASE address. This is currently set to
DRAM_BASE+128MB for the FVP.

The modified implementation uses the IO abstraction rather than
making direct semi-hosting calls. The semi-hosting driver is now
registered for the FVP platform during initialisation of each boot
stage where it is used. Additionally, the FVP platform includes a
straightforward implementation of 'plat_get_image_source' which
provides a generic means for the 'load_image' function to determine
how to access the image data.

The FVP platform has a few filenames that begin with fvp_. These are
renamed to plat_ to make it easier to use the FVP port as a template.
