The i.MX 8MP Media Applications Processor is part of the growing
i.MX8M family targeting the consumer and industrial market. It brings
an effective Machine Learning and AI accelerator that enables a new
class of applications. It is built in 14LPP to achieve both high
performance and low power consumption and relies on a powerful fully
coherent core complex based on a quad core Arm Cortex-A53 cluster and
Cortex-M7 low-power coprocessor, audio digital signal processor, machine
learning and graphics accelerators.

Although the GPC provides the similar functions for all the
i.MX8M SoC family, the HW register offset and bit defines
still have some slight difference, so move the hw reg
offset & most of the bitfield defines in 'gpc_reg.h' that
is specific to each SoC.

This patch performs the following:
- Creating two corstone700 platforms under corstone700 board:
fvp and fpga
- Since the FVP and FPGA have IP differences, this commit provides a specific DTS for each platform
- The platform can be specified using the TARGET_PLATFORM Makefile variable
(possible values are: fvp or fpga)
- Allowing to use u-boot by:
- Enabling NEED_BL33 option
- Fixing non-secure image base: For no preloaded bl33 we want to
have the NS base set on shared ram. Setup a memory map region
for NS in shared map and set the bl33 address in the area.
- Setting the SYS_COUNTER_FREQ_IN_TICKS based on the selected
platform
- Setting ARM_MAP_SHARED_RAM and ARM_MAP_NS_SHARED_RAM to use MT_MEMORY

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.

SCMI shared memory is used to exchange message payloads between
secure SCMI services and non-secure SCMI agents. It is mapped
uncached (device) mainly to conform to existing support in
the Linux kernel. Note that executive messages are mostly short
(few 32bit words) hence not using cache will not penalize much
performances.
Platform stm32mp1 shall configure ETZPC to harden properly the
secure and non-secure areas of the SYSRAM address space, that before
CPU accesses the shared memory when mapped non-secure.
This change defines STM32MP_SEC_SYSRAM_BASE/STM32MP_SEC_SYSRAM_SIZE and
STM32MP_NS_SYSRAM_BASE/STM32MP_NS_SYSRAM_SIZE.

Disable use of Neon VFP support for platform stm32mp1 when
building with SP_MIN runtime services as these can conflict with
non-secure world use of NEON support. This is preferred over a
systematic backup/restore of NEON context when switching
between non-secure and secure worlds.
When NEON support is disabled, this is done for both BL2 and BL32 as
build process uses common libraries built once for both binaries.
