dts: stm32mp157c: fix etzpc node location in DTSI file
Fix etzpc node location in stm32mp157c DTSI file as requested during the
patch review. The comment was addressed then fixup change discarded while
rebasing.
Use ETZPC driver to configure secure aware interfaces to assign
them to non-secure world. Sp_min also configures BootROM resources
and SYSRAM to assign both to secure world only.
Define stm32mp15 SoC identifiers for the platform specific DECPROT
instances.
ETZPC stands for Extended TrustZone Protection Controller. It is a
resource conditional access device. It is mainly based on Arm TZPC.
ST ETZPC exposes memory mapped DECPROT cells to set access permissions
to SoC peripheral interfaces as I2C, SPI, DDR controllers, and some
of the SoC internal memories.

xlat_tables_v2: add base table section name parameter for spm_mm

TF-A: Fix BL31 linker script error
The patch fixes BL31 linker script error
"Init code ends past the end of the stacks"
for platforms with number of CPUs less than 4,
which is caused by __STACKS_END__ address being
lower than __INIT_CODE_END__.
The modified BL31 linker script detects such cases
and increases the total amount of stack memory,
setting __STACKS_END__ = __INIT_CODE_END__, and
CPUs' stacks are calculated by BL31 'plat_get_my_stack'
function accordingly. For platforms with more than 4 CPUs
and __INIT_CODE_END__ < __STACKS_END__ stack memory does not
increase and allocated CPUs' stacks match the existing

This change uses the shift info to shift the mask before it is used,
allowing clock selector register bit fields to be spread on the 32 bits
of the register as long as the mask fits in 8 contiguous bit at most.

Oscillators, PLLs and some system clocks can be related straight to
