Clarify EL3 payload documentation

Disable PL011 UART before configuring it

update SPM/DCM/MTCMOS related code for power control logic

This patch reworks the section about booting an EL3 payload in the
User Guide:

 - Centralize all EL3 payload related information in the same
   section.

 - Mention the possibility to program the EL3 payload in flash memory
   and execute it in place.

 - Provide model parameters for both the Base and Foundation FVPs.

 - Provide some guidance to boot an EL3 payload on Juno.

We found sometimes mtcmos operation is too long in spm (>1ms),
so update a new version to fix it.
I verified with 5 hours power_LoadTest, every mtcmos control
can finish in 500us (average is 100~200us).

cdefs.h: Use __deprecated__ instead of deprecated

ARM plat: add build option to unlock access to non-secure timer

The PL011 TRM (ARM DDI 0183G) specifies that the UART must be
disabled before any of the control registers are programmed. The
PL011 driver included in TF does not disable the UART, so the
initialization in BL2 and BL31 is violating this requirement
(and potentially in BL1 if the UART is enabled after reset).

This patch modifies the initialization function in the PL011
console driver to disable the UART before programming the
control registers.

Register clobber list and documentation updated.

Fixes ARM-software/tf-issues#300

Use the form with underscores to define the '__deprecated' macro to avoid
collisions with potentially defined macros, as suggested in gcc docs
(https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html#Attribute-Syntax

).

Currently, Trusted Firmware on ARM platforms unlocks access to the
timer frame registers that will be used by the Non-Secure world. This
unlock operation should be done by the Non-Secure software itself,
instead of relying on secure firmware settings.

This patch adds a new ARM specific build option 'ARM_CONFIG_CNTACR'
to unlock access to the timer frame by setting the corresponding
bits in the CNTACR<N> register. The frame id <N> is defined by
'PLAT_ARM_NSTIMER_FRAME_ID'. Default value is true (unlock timer
access).

Documentation updated accordingly.

Rearrange fields in TF data structures to reduce padding

Add support for ARM Cortex-A35 processor

Various documentation fixes

This patch adds a brief description of 'MAX_MMAP_REGIONS' and
'ADDR_SPACE_SIZE' to the Porting Guide. These fields must be defined
by the platform in order to use the translation table library.

Change-Id: Ida366458fe2bc01979091a014dc38da0fae5991e

This patch rearranges fields of the `image_desc_t` & `auth_img_desc_t`
data structures to reduce padding between the fields and thereby
save memory.

NOTE: Platform ports which anonymously initialize these structures
should be aware of the rearrangement and do the required
modification.

This patch changes the anonymous initialization of `rt_svc_desc_t` structure
by the `DECLARE_RT_SVC` macro to designated initialization. This makes the
code more robust and less sensitive to potential changes to the
`rt_svc_desc_t` structure.

The help message printed by the cert_create tool using the command
line option -h (or --help) does not correctly list all the available
command line options.

This patch reworks the print_help() function to print the help
messages in a data driven approach. For each command line option
registered, an optional help message can be specified, which will
be printed by print_help().

Help messages for the TBBR options (certificates, keys and images)
are also provided.

Fix a small bug in the short options string passed to getopt_long:
the ':' was missing in the '-a' option (this option must take an
argument).
