Add helper to parse BL31 parameters (both versions)
...
BL31 used to take a single bl31_params_t parameter structure with entry
point information in arg0. In commit 726002263 (Add new version of image
loading.) this API was changed to a more flexible linked list approach,
and the old parameter structure was copied into all platforms that still
used the old format. This duplicated code unnecessarily among all these
platforms.
This patch adds a helper function that platforms can optionally link to
outsource the task of interpreting arg0. Many platforms are just
interested in the BL32 and BL33 entry point information anyway. Since
some platforms still need to support the old version 1 parameters, the
helper will support both formats when ERROR_DEPRECATED == 0. This allows
those platforms to drop a bunch of boilerplate code and asynchronously
update their BL2 implementation to the newer format.

Factor out cross-BL API into export headers suitable for 3rd party code
...
This patch adds a new include/export/ directory meant for inclusion in
third-party code. This is useful for cases where third-party code needs
to interact with TF-A interfaces and data structures (such as a custom
BL2-implementation like coreboot handing off to BL31). Directly
including headers from the TF-A repository avoids having to duplicate
all these definitions (and risk them going stale), but with the current
header structure this is not possible because handoff API definitions
are too deeply intertwined with other TF code/headers and chain-include
other headers that will not be available in the other environment.
The new approach aims to solve this by separating only the parts that
are really needed into these special headers that are self-contained and
will not chain-include other (non-export) headers. TF-A code should
never include them directly but should instead always include the
respective wrapper header, which will include the required prerequisites
(like <stdint.h>) before including the export header. Third-party code
can include the export headers via its own wrappers that make sure the
necessary definitions are available in whatever way that environment can
provide them.

Use explicit-width data types in AAPCS parameter structs
...
It's not a good idea to use u_register_t for the members of
aapcs64_params_t and aapcs32_params_t, since the width of that type
always depends on the current execution environment. This would cause
problems if e.g. we used this structure to set up the entry point of an
AArch32 program from within an AArch64 program. (It doesn't seem like
any code is doing that today, but it's probably still a good idea to
write this defensively. Also, it helps with my next patch.)

arm: Shorten the Firmware Update (FWU) process
...
The watchdog is configured with a default value of 256 seconds in order
to implement the Trusted Board Boot Requirements.
For the FVP and Juno platforms, the FWU process relies on a watchdog
reset. In order to automate the test of FWU, the length of this process
needs to be as short as possible. Instead of waiting for those 4 minutes
to have a reset by the watchdog, tell it to reset immediately.
There are no side effects as the value of the watchdog's load register
resets to 0xFFFFFFFF.
Tested on Juno.

Introduce lightweight BL platform parameter library
...
This patch adds some common helper code to support a lightweight
platform parameter passing framework between BLs that has already been
used on Rockchip platforms but is more widely useful to others as well.
It can be used as an implementation for the SoC firmware configuration
file mentioned in the docs, and is primarily intended for platforms
that only require a handful of values to be passed and want to get by
without a libfdt dependency. Parameters are stored in a linked list and
the parameter space is split in generic and vendor-specific parameter
types. Generic types will be handled by this code whereas
vendor-specific types have to be handled by a vendor-specific handler
function that gets passed in.
