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.

The comments with the prototypes of the register functions of the
console drivers are incorrect. The arguments are wrong. This patch fixes
them.

Introduce object pool allocator ...

The object pool allocator provides a simplistic interface to manage
allocation in a fixed-size static array. The caller creates a static
"object pool" out of such an array and may then call pool_alloc() to
get the next available object within the pool. There is also a variant
to get multiple consecutive objects: pool_alloc_n().

Note that this interface does not provide any way to free the objects
afterwards. This is by design and it is not a limitation. We do not
want to introduce complexity induced by memory freeing, such as
use-after-free bugs, memory fragmentation and so on.

psci: platform control of SYSTEM_SUSPEND entry ...

Some platforms can only resume from system suspend from the boot
CPU, hence they should only enter that state from that same core.

The following commit presents an interface that allows the platform to
reject system suspend entry near its very last stage (last CPU).

PSCI: Do not flush cache when unneeded ...

When a platform enables its caches before it accesses the
psci_non_cpu_pd_nodes structure then explicit cache maintenance
is not needed.

drivers: imx: mxc_usdhc: Do not set MMC_RSP_48 for MMC_RESPONSE_R2 ...

commit 97d5db8 reverts an update to the
MMC layer that accompanied the original submission of this MMC driver this
is the right-thing-to-do in terms of the MMC spec.

Unfortunately the reversion also breaks this driver. The issue is the i.MX
controller doesn't want MMC_RSP_48 set for MMC_RESPONSE_R2.

The appropriate place to place that constraint is obviously in
drivers/imx/usdhc/imx_usdhc.c not in the shared MMC codebase. This patch
restores the logic the i.MX controller requires without breaking it for
everyone else.

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.
