add support for the remoteproc control feature for the external system
With this feature we can switch on/off the external system on demand:
echo stop > /sys/class/remoteproc/remoteproc0/state
echo start > /sys/class/remoteproc/remoteproc0/state
During Linux boot the remoteproc subsystem automatically start
the external system. The user can use the commands above to
stop then start the remote core.

By building the Corstone-1000 firmware under the firmware multiconfig we
can also build a minimal standard core image to be mounted in the fvp as
a mass storage device.
To do this we had to enable the MMC card interface in the Corstone-1000
kernel configuration.

oe-core master has upgraded from 6.5 to 6.6, but as we have BSPs that
still use 6.5 (corstone1000, n1sdp) we need to carry the recipe. This
should be a short-term measure as 6.5 was EOL in December 2023.
Also, drop the unused 6.4 linux-yocto which was no longer needed since
N1SDP moved to 6.5 with 21df60b.

When booting, the tee driver from kernel side
invokes a yielding call to OP-TEE, which gets
stuck because OP-TEE never sends Done response:
OPTEE_FFA_YIELDING_CALL_RETURN_DONE
This issue was previously resolved by introducing
an inappropriate patch to the kernel with 1 ms delay
in ffa_msg_send_direct_req.
Further investigation proved that OP-TEE doesn't
get enough processing time and is constantly interrupted
by the kernel requests. To remove this patch, TF-A logging
level is lowered to default (40 in debug builds and
20 in release builds), which eliminates the time consumed
previously by TF-A VERBOSE logs (giving OP-TEE more
processing time).

Arm generic timer provides different timers for different exception
levels and different secure states. Because Armv8-R AArch64 has secure
state only, the valid timer for hypervisor in EL2 is secure hypervisor
physical timer. But for platform fvp-baser-aemv8r64, before FVP 11.18,
the secure hypervisor physical timer could not work well in EL2, so we
had been using Non-secure physical timer in EL2 for hypervisor as a
workaround.
Since secure hypervisor physical timer issue has been fixed from FVP
11.18, we can use this correct timer in EL2 for hypervisor now. So we
update the device tree timer node to use secure hypervisor physical
timer interrupt for hypervisor.
About the interrupt assignments of FVP, please refer to

The 64-bit fvp-base machine uses the upstream fvp-base-recv devicetree,
but fvp-base-arm32 was accidentally using the old
fvp-base-gicv3-psci-custom that we patch into the kernel.
As the only difference between these platforms at a "hardware" level is
whether the cores boot in 32- or 64-bit mode, they should both use
fvp-base-revc.
This isn't trivial as devicetree files need to be under the correct
arch/ directory, so we need to symlink into arch/arm the right files
from arch/arm64.
This has several improvements, but primarily virtio networking works so
we can now use testimage with fvp-base-arm32.

This commit introduces a new kernel patch that aligns the FF-A
versions checks according to the FF-A specification v1.0.
Without this fix, the FF-A bus fails to initialize when the FF-A
framework is version 1.1 (comes with the latest TF-A).
The bus driver which is v1.0 rejects the framework v1.1 despite
the fact they are compatible according to the specification.
This kernel patch changes the logic of the version checking based on
the specification.
