Rename 'smcc' to 'smccc'

When the source code says 'SMCC' it is talking about the SMC Calling
Convention. The correct acronym is SMCCC. This affects a few definitions
and file names.

Some files have been renamed (smcc.h, smcc_helpers.h and smcc_macros.S)
but the old files have been kept for compatibility, they include the
new ones with an ERROR_DEPRECATED guard.

BL1: Deprecate the `bl1_init_bl2_mem_layout()` API

The `bl1_init_bl2_mem_layout()` API is now deprecated. The default weak
implementation of `bl1_plat_handle_post_image_load()` calculates the
BL2 memory layout and populates the same in x1(r1). This ensures
compatibility for the deprecated API.

Add image_id to bl1_plat_handle_post/pre_image_load()

This patch adds an argument to bl1_plat_post/pre_image_load() APIs
to make it more future proof. The default implementation of
these are moved to `plat_bl1_common.c` file.

These APIs are now invoked appropriately in the FWU code path prior
to or post image loading by BL1 and are not restricted
to LOAD_IMAGE_V2.

The patch also reorganizes some common platform files. The previous
`plat_bl2_el3_common.c` and `platform_helpers_default.c` files are
merged into a new `plat_bl_common.c` file.

NOTE: The addition of an argument to the above mentioned platform APIs
is not expected to have a great impact because these APIs were only
recently added and are unlikely to be used.

Report errata workaround status to console

The errata reporting policy is as follows:

- If an errata workaround is enabled:

- If it applies (i.e. the CPU is affected by the errata), an INFO
message is printed, confirming that the errata workaround has been
applied.

- If it does not apply, a VERBOSE message is printed, confirming
that the errata workaround has been skipped.

- If an errata workaround is not enabled, but would have applied had
it been, a WARN message is printed, alerting that errata workaround
is missing.

The CPU errata messages are printed by both BL1 (primary CPU only) and
runtime firmware on debug builds, once for each CPU/errata combination.

Relevant output from Juno r1 console when ARM Trusted Firmware is built
with PLAT=juno LOG_LEVEL=50 DEBUG=1:

This patch adds generic changes in BL1 to support AArch32 state.
New AArch32 specific assembly/C files are introduced and
some files are moved to AArch32/64 specific folders.
BL1 for AArch64 is refactored but functionally identical.
BL1 executes in Secure Monitor mode in AArch32 state.

NOTE: BL1 in AArch32 state ONLY handles BL1_RUN_IMAGE SMC.

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.
