Compile with CFG_CORE_SEL2_SPMC=y

Note that this is an experimental feature, ABIs etc may have
incompatible changes.

This depends on using the FF-A v4 patchset in the Linux kernel.

core: spmc: FF-A ABI updates

Updates structs and definitions to follow FF-A version 1.0.

Use the special hard coded UUID (486178e0-e7f8-11e3-bc5e-0002a5d5c51b)
for the SP OP-TEE is when compiled for FF-A.

Updates the FF-A OP-TEE message ABI to make room for struct
optee_msg_arg to be used for RPC for OPTEE_FFA_YIELDING_CALL_WITH_ARG.

struct thread_ctx::rpc_arg for the current thread will always hold a
pointer to the struct optee_msg_arg to be used for RPC.

With this allocation of shared memory can be pushed up one layer and be
done via the struct optee_msg_arg so the
OPTEE_FFA_YIELDING_CALL_RETURN_ALLOC_*_SHM and
OPTEE_FFA_YIELDING_CALL_RETURN_FREE_*_SHM can be removed making the FF-A
ABI a bit less complicated.

Changes OPTEE_FFA_UNREGISTER_SHM to be a blocking call instead of a
yielding call.

Removes the unused OPTEE_FFA_YIELDING_CALL_REGISTER_SHM.

Updates the return values from yielding calls to use the TEE_Result
values instead of FF-A one to use the error code from the correct layer.

Defines OPTEE_MSG_FMEM_INVALID_GLOBAL_ID to 0xffffffffffffffffff which
is used as an invalid global id instead of 0.

This is an ABI breakage which must be done in sync with the FF-A v4
patchset in the Linux kernel.

core: dt: split dt_get_irq() between interrupt framework and drivers

To welcome other interrupt drivers (coming from other platform for
example), we need to rework dt_get_irq() which was dedicated to ARM
platform more specifically GIC driver.
This change moves dt_get_irq() in interrupt framework, this manages the
generic part of interrupt bindings (specified by devicetree.org [1]) and
then call a driver callback to translate specific properties.
This callback is registered by drivers while its init step.

Update CAAM crypto driver accordingly.

When a ctx of a single instance user TA is first created,
lock_single_instance() is called in tee_ta_try_set_busy().
However, unlock_single_instance() is not called in

It results that tee_ta_single_instance_thread is not reset
when CFG_CONCURRENT_SINGLE_INSTANCE_TA is not enabled.
So remove the wrong conditional expression and remove
"initializing" from tee_ta_ctx since it's no longer used.
