GIC setup code which used to be in bl31_plat_setup.c is now in fvp_gic.c
to simplify future changes to other bootloader stages. This patch moves
code from bl31_plat_setup.c to fvp_gic.c, simplifies the include file
list for bl31_plat_setup.c, moves GIC declarations from the bl31.h header
file into the platform.h, and reworks files according to coding style
guide.

Platform setup code has to reserve some memory for storing the
memory layout information. It is populated in early platform setup
code.
blx_get_sec_mem_layout() functions used to return a copy of this
structure. This patch modifies blx_get_sec_mem_layout() functions
so that they now directly return a pointer to their memory layout
structure. It ensures that the memory layout returned by
blx_get_sec_mem_layout() is always up-to-date and also avoids a
useless copy of the meminfo structure.
Also rename blx_get_sec_mem_layout() to blx_plat_sec_mem_layout()
to make it clear those functions are platform specific.

This patch makes sure the C runtime environment is properly
initialised before executing any C code.
- Zero-initialise NOBITS sections (e.g. the bss section).
- Relocate BL1 data from ROM to RAM.

- Check at link-time that bootloader images will fit in memory
at run time and that they won't overlap each other.
- Remove text and rodata orphan sections.
- Define new linker symbols to remove the need for platform setup
code to know the order of sections.
- Reduce the size of the raw binary images by cutting some sections
out of the disk image and allocating them at load time, whenever
possible.
- Rework alignment constraints on sections.
- Remove unused linker symbols.
- Homogenize linker symbols names across all BLs.
- Add some comments in the linker scripts.

Global and static variables are expected to be initialised to zero
by default. This is specified by the C99 standard. This patch
removes some unnecessary initialisations of such variables.
It fixes a compilation warning at the same time:
plat/fvp/bl31_plat_setup.c:82:3: warning: missing braces around
initializer [-Wmissing-braces]
section("tzfw_coherent_mem"))) = {0};
^
plat/fvp/bl31_plat_setup.c:82:3: warning: (near initialization for
‘ns_entry_info[0]’) [-Wmissing-braces]
Note that GCC should not have emitted this warning message in the
first place. The C Standard permits braces to be elided around
subaggregate initializers. See this GCC bug report:
