Move plat/common source file definitions to generic Makefiles

These source file definitions should be defined in generic
Makefiles so that all platforms can benefit. Ensure that the
symbols are properly marked as weak so they can be overridden
by platforms.

NOTE: This change is a potential compatibility break for
non-upstream platforms.

AArch32: Add generic changes in BL2

This patch adds generic changes in BL2 to support AArch32 state.
New AArch32 specific assembly/C files are introduced and
some files are moved to AArch32/64 specific folders.
BL2 for AArch64 is refactored but functionally identical.

BL2 executes in Secure SVC mode in AArch32 state.

Changes for new version of image loading in BL1/BL2

This patch adds changes in BL1 & BL2 to use new version
of image loading to load the BL images.

Following are the changes in BL1:
-Use new version of load_auth_image() to load BL2
-Modified `bl1_init_bl2_mem_layout()` to remove using
`reserve_mem()` and to calculate `bl2_mem_layout`.
`bl2_mem_layout` calculation now assumes that BL1 RW
data is at the top of the bl1_mem_layout, which is more
restrictive than the previous BL1 behaviour.

Following are the changes in BL2:
-The `bl2_main.c` is refactored and all the functions
for loading BLxx images are now moved to `bl2_image_load.c`
`bl2_main.c` now calls a top level `bl2_load_images()` to
load all the images that are applicable in BL2.
-Added new file `bl2_image_load_v2.c` that uses new version
of image loading to load the BL images in BL2.

All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.

This patch moves the assembly exclusive lock library code

A stub file which includes the file from new location is

makefiles are also modified to include the file from the new
location.

Move include and source files to logical locations

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.

Separate out BL2, BL3-1 and BL3-2 early exception vectors from BL1

bl1/aarch64/early_exceptions.S used to be re-used by BL2, BL3-1 and
BL3-2. There was some early SMC handling code in there that was not
required by the other bootloader stages. Therefore this patch
introduces an even simpler exception vector source file for BL2,
BL3-1 and BL3-2.

Specify image entry in linker script

At present, the entry point for each BL image is specified via the
Makefiles and provided on the command line to the linker. When using a
link script the entry point should rather be specified via the ENTRY()
directive in the link script.

This patch updates linker scripts of all BL images to specify the entry
point using the ENTRY() directive. It also removes the --entry flag
passed to the linker through Makefile.

Update Makefiles to get proper dependency checking working.

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.
