plat/arm : update BL size macros to give BL1 and BL2 more space for TBB ...

For Trusted Board Boot, BL1 RW section and BL2 need more space to
support the ECDSA algorithm. Specifically, PLAT_ARM_MAX_BL1_RW_SIZE
is increased on ARM platforms.

And on the Juno platform:
    - BL2 size, PLAT_ARM_MAX_BL2_SIZE is increased.
    - SCP_BL2 is loaded into the space defined by BL31_BASE ->
      BL31_RW_BASE. In order to maintain the same size space for
      SCP_BL2,PLAT_ARM_MAX_BL31_SIZE is increased.

xlat: simplify mmap_add_region_check parameters (#1101) ...

Use a mmap_region_t as parameter instead of getting a parameter for each
structure member. This reduces the scope of changes when adding members
to mmap_region_t.

Also align on the convention of using mm_cursor as a variable name for
the currently inspected region when iterating on the region array.

plat/arm: Fix BL31_BASE when RESET_TO_BL31=1

plat/arm: Fix BL31_BASE when RESET_TO_BL31=1 ...

The value of BL31_BASE currently depends on the size of BL31. This
causes problems in the RESET_TO_BL31 case because the value of
BL31_BASE is used in the model launch parameters, which often changes.

Therefore, this patch fixes BL31_BASE to the middle of Trusted SRAM,
to avoid further model parameter changes in future.

xlat: Use MAP_REGION macro as compatibility layer ...

Use the MAP_REGION to build the mmap_region_t argument in wrappers like
mmap_add_region(). Evolution of the mmap_region_t might require adding
new members with a non-zero default value. Users of MAP_REGION are
protected against such evolution. This commit also protects users of
mmap_add_region() and mmap_add_dynamic_region() functions against these
evolutions.

Also make the MAP_REGION macro implementation more explicit and make it
a mmap_region_t compound literal to make it useable as a function
parameter on its own and to prevent using it in initialization of
variables of different type.

Implement log framework ...

This patch gives users control over logging messages printed from the C
code using the LOG macros defined in debug.h Users now have the ability
to reduce the log_level at run time using the tf_log_set_max_level()
function. The default prefix string can be defined by platform by
overriding the `plat_log_get_prefix()` platform API which is also
introduced in this patch.

The new log framework results in saving of some RO data. For example,
when BL1 is built for FVP with LOG_LEVEL=LOG_LEVEL_VERBOSE, resulted
in saving 384 bytes of RO data and increase of 8 bytes of RW data. The
framework also adds about 108 bytes of code to the release build of FVP.
