plat: stm32mp2: make the platform ready to compile with SCP-Fw

STM32MP2 could use SCP-Fw to handle SCMI messages. By default this is
disabled, but it could be enable with these config:
CFG_SCMI_SCPFW=y
CFG_SCP_FIRMWARE=<path_to_SCP-Fw_srcs>

On STM32MP2, OP-TEE use the resources describe in the "scmi" device-tree
node to configure SCP-Fw.

scmi: Fix qemu_v8 configuration

OP-TEE SCMI server on qemu_v8 doesn't boot with latest SCP-firmware when

This comes from that there is no notification channel supported yet for
OP-TEE SCMI server. Disable notification until notification support is
added.

core/scmi: export sub.mk files in SCP-firmware

In order to ease the update of makefile when C or Header files of
SCP-firmware project changes, we integrate them in the optee subdirectory
of SCP-firmware.

sub-optee-fvp.mk and sub-optee-stm32mp1.mk are moved unchanged in their
product directories of SCP-repository.

scmi-server/sub.mk is split:
- macro and compilation flags stay in optee-os
- srcs and incdirs are moved in product/optee directory

All modules and products related to optee are located in the
product/optee directory in the SCP-firmware repository, adding an "optee-"
prefix in the product name is useless. Remove it.

the ci will temporary point to the sha1 of the merged MR branch of
SCP-firmware. This will be replaced with next SCP-firmware tag v2.15.0
once released.

SCMI-Server is built upon the SCP-firmware source tree and
a recent change [1] being proposed is moving functionalities

This patch adds support to fetch those additional files based
on two options:
CFG_SCPFW_SCMI_PERF_FAST_CHANNELS (existing)
CFG_SCPFW_SCMI_PERF_PROTOCOL_OPS (new)

core: lib: scmi-server: Build a SCMI server from SCP-firmware

Adds build of an SCMI server library using SCP-firmware source tree
upon boolean configuration switch CFG_SCMI_SCPFW. Platform must set
the SCP firmware target product with CFG_SCMI_SCPFW_PRODUCT and the
root path of the SCP-firmware source tree with CFG_SCP_FIRMWARE.

CFG_SCMI_SCPFW and CFG_SCMI_MSG_DRIVERS are exclusives alternate
implementations of SCMI services. The former implements almost all
the SCMI specification while the later implements only basic SCMI
services.

SCP-firmware is configured with CMake as an external project to
generate the embedded module resource source and header files to
be built with SCP-firmware.

This commit integrates the 2 SCP-firmware products designed for OP-TEE
in SCP-firmware source tree. Product optee-fvp targets platform vexpress
flavors FVP and Qemus. Product optee-stm32mp1 targets platform stm32mp1.
