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 implements a set of handlers in the SPD which are called by
the PSCI runtime service upon receiving a power management
operation. These handlers in turn pass control to the Secure Payload
image if required before returning control to PSCI. This ensures that
the Secure Payload has complete visibility of all power transitions in
the system and can prepare accordingly.

This patch adds the TSPD service which is responsible for managing
communication between the non-secure state and the Test Secure Payload
(TSP) executing in S-EL1.
The TSPD does the following:
1. Determines the location of the TSP (BL3-2) image and passes control
to it for initialization. This is done by exporting the 'bl32_init()'
function.
2. Receives a structure containing the various entry points into the TSP
image as a response to being initialized. The TSPD uses this
information to determine how the TSP should be entered depending on
the type of operation.
3. Implements a synchronous mechanism for entering into and returning
from the TSP image. This mechanism saves the current C runtime
context on top of the current stack and jumps to the TSP through an
ERET instruction. The TSP issues an SMC to indicate completion of the
previous request. The TSPD restores the saved C runtime context and
resumes TSP execution.
This patch also introduces a Make variable 'SPD' to choose the specific
SPD to include in the build. By default, no SPDs are included in the
build.
