Introduce helper functions stm32mp_register_secure_periph_iomem()
and stm32mp_register_non_secure_periph_iomem() for drivers to
register a resource as secure or non-secure based on its SoC
interface registers base address.

These functions are stubbed when shared resources driver is not
embedded (!STM32MP_SHARED_RESOURCES) so that drivers embedded
in other BL stages do not bother whether they shall register or
not their resources.

Define helper functions stm32mp_register_secure_periph() and
stm32mp_register_non_secure_periph() for platform drivers to
register a shared resource assigned to respectively secure
or non-secure world.

Some resources are related to clock resources. When a resource is
registered as secure, ensure its clock dependencies are also
registered as secure. Registering a non-secure resource does not
mandate its clock dependencies are also registered as non-secure.

Fix all external broken links reported by Sphinx linkcheck tool.

The TF-A firmware build system is capable of building on both Unix like
and Windows host PCs. The commit ID 7ff088 "Enable MTE support" updated
the Makefile to conditionally enable the MTE support if the AArch64
architecture revision was greater than 8.5. However, the Makefile changes
were dependent on shell commands that are only available on unix shells,
resulting in build failures on a Windows host PC.

This patch fixes the Makefile by using a more portable approach for
comparing the architecture revision.

structure retrieved from fw_config device tree.
This patch fixes coverity defect:360213.

Also, removed conditional calling of "fconf_populate" as "fconf_populate"
function already checks the validity of the device tree address received
and go to panic in case of address is NULL.

The .rela.dyn section is the same for BL2-AT-EL3, BL31, TSP.

Move it to the common header file.

I slightly changed the definition so that we can do "RELA_SECTION >RAM".
It still produced equivalent elf images.

Please note I got rid of '.' from the VMA field. Otherwise, if the end
of previous .data section is not 8-byte aligned, it fails to link.

The plat_core_pos_by_mpidr() implementation for the Arm FPGA port has
some issues, which leads to problems when matching GICv3 redistributors
with cores:
- The power domain tree was not taking multithreading into account, so
  we ended up with the wrong mapping between MPIDRs and core IDs.
- Before even considering an MPIDR, we try to make sure Aff2 is 0.
  Unfortunately this is the cluster ID when the MT bit is set.
- We mask off the MT bit in MPIDR, before basing decisions on it.
- When detecting the MT bit, we are properly calculating the thread ID,
  but don't account for the shift in the core and cluster ID checks.

Those problems lead to early rejections of MPIDRs values, in particular
when called from the GIC code. As a result, CPU_ON for secondary cores
was failing for most of the cores.

Fix this by properly handling the MT bit in plat_core_pos_by_mpidr(),
also pulling in FPGA_MAX_PE_PER_CPU when populating the power domain
tree.

Neoverse N1 erratum 1800710 is a Cat B erratum, present in older
revisions of the Neoverse N1 processor core.  The workaround is to
set a bit in the ECTLR_EL1 system register, which disables allocation
of splintered pages in the L2 TLB.
