Add new version of image loading.

This patch adds capability to load BL images based on image
descriptors instead of hard coded way of loading BL images.
This framework is designed such that it can be readily adapted
by any BL stage that needs to load images.

In order to provide the above capability the following new
platform functions are introduced:

bl_load_info_t *plat_get_bl_image_load_info(void);
This function returns pointer to the list of images that the
platform has populated to load.

bl_params_t *plat_get_next_bl_params(void);
This function returns a pointer to the shared memory that the
platform has kept aside to pass trusted firmware related
information that next BL image needs.

void plat_flush_next_bl_params(void);
This function flushes to main memory all the params that
are passed to next image.

int bl2_plat_handle_post_image_load(unsigned int image_id)
This function can be used by the platforms to update/use
image information for given `image_id`.

`desc_image_load.c` contains utility functions which can be used
by the platforms to generate, load and executable, image list
based on the registered image descriptors.

This patch also adds new version of `load_image/load_auth_image`
functions in-order to achieve the above capability.

Following are the changes for the new version as compared to old:
- Refactor the signature and only keep image_id and image_info_t
arguments. Removed image_base argument as it is already passed
through image_info_t. Given that the BL image base addresses and
limit/size are already provided by the platforms, the meminfo_t
and entry_point_info arguments are not needed to provide/reserve
the extent of free memory for the given BL image.

- Added check for the image size against the defined max size.
This is needed because the image size could come from an
unauthenticated source (e.g. the FIP header).
To make this check, new member is added to the image_info_t
struct for identifying the image maximum size.

New flag `LOAD_IMAGE_V2` is added in the Makefile.
Default value is 0.

NOTE: `TRUSTED_BOARD_BOOT` is currently not supported when
`LOAD_IMAGE_V2` is enabled.

Document: add PLAT_PARTITION_MAX_ENTRIES define

Partition driver requires the "PLAT_PARTITION_MAX_ENTRIES" definition.

By default, it's defined to 128 in partition driver. But it costs a lot
of memory, and only a few partition entries are really used in platform
partition table. If user wants use memory efficiently, user should
define the build flag in platform.mk instead.

Add some missing forward declarations in plat_arm.h

This patch adds a couple of missing forward declarations in plat_arm.h
so that all types it references are known within this header file,
without relying on previous header inclusions. This concerns the
meminfo and bl31_params structures, which are defined in bl_common.h.
Other external types referenced from plat_arm.h (e.g. mmap_region_t)
get declared through header files included by arm_plat.h so they
don't need forward declarations.

Commit e8719552a24 removed some definitions related to translation

Ensure PMF service timestamps are properly aligned on a cache line boundary

When using more than a single service in PMF, it is necessary that the
per-service timestamps begin on a cache line boundary. Previously it
was possible that two services shared a cache line for their
timestamps. This made it difficult to reason about cache maintenance
operations within a single service and required a global understanding
of how all services operate.
