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.

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).

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.

- This commit provides a recipe for the FF-A Debugfs Linux
driver v2.1.0.
The driver is an out-of-tree loadable modules. It exposes
FF-A operations to user space and only used for development
purposes.
- Create a dev package for ffa-debugfs-mod
ffa-debugfs-mod recipe provides arm_ffa_user.h header for
other recipes that need it at build time.
The header is put in ffa-debugfs-mod-dev package.
