scmi: Optimize bakery locks when HW_ASSISTED_COHERENCY is enabled ...

When HW_ASSISTED_COHERENCY is enabled we can use spinlocks
instead of using the more complex and slower bakery algorithm.

plat/arm/css/sgm: Reorder early platform init

Replace S-EL3 references by EL3 ...

The "Secure" prefix (S-ELx) is valid only for S-EL0 and S-EL1 but is
meaningless for EL3, since EL3 is always secure. Hence, the "S" prefix
has been removed from wherever it was used as "S-EL3".

plat/arm/css/sgm: Reorder early platform init ...

In the function, bl1_early_platform_setup in the file
plat/arm/css/sgm/sgm_bl1_setup.c:

  plat_config_init();

  arm_bl1_early_platform_setup();

The debug messages logged by plat_config_init() are lost because
the console is initialized in the function
arm_bl1_early_platform_setup()

To see the logs of plat_config_init, this fix re-orders above calls
so that the console is initialized before call to plat_config_init.

plat/arm: Move norflash driver to drivers/ folder ...

This way it can be reused by other platforms if needed.

Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.

Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

marvell: Move BLE from external repo to the platform folder ...

The BLE is the pre-TF-A boot stage required by Marvell Armada
BootROM for bringing up DRAM and allow the boot image copy to it.
Since this is not a standard boot level and only uses the TF-A
as a build environment, it was introduced out of source tree.
However it turns out that such remote location introduces additional
complexity to the upstream TF-A build process.
In order to simplify the build environment the BLE source folder
is relocated from the external repository to A8K platform directory.
The build documentation is updated accordingly.

FVP: Reclaim init code for the stack ...

Map the initialization code for BL31 to overlap with the memory
required for the secondary cores stack. Once BL31 has been
initialized the memory can be remapped to RW data so that it can
be used for secondary cores stacks. By moving code from .text to
.text.init the size of the BL31 image is decreased by a page.

Split arm_common.ld.S into two linker scripts, one for tzc_dram
(arm_tzc_dram.ld.S) and one for reclaiming initialization code
(arm_reclaim_init.ld.S) so that platforms can chose which memory
regions they wish to include.

plat/arm: Remove option ARM_BOARD_OPTIMISE_MEM ...

This option makes it hard to optimize the memory definitions of all Arm
platforms because any change in the common defines must work in all of
them. The best thing to do is to remove it and move the definition to
each platform's header.

FVP, SGI and SGM were using the definitions in board_arm_def.h. The
definitions have been copied to each platform's platform_def.h. Juno
was already using the ones in platform_def.h, so there have been no
changes.
