core: rpmb: handle not-implemented error code on device probing

Consider that non-secure world may report TEE_ERROR_NOT_IMPLEMENTED
error code on OPTEE_RPC_CMD_RPMB_PROBE_RESET RPC command when that
RPC command is not supported. This is needed to support U-Boot
that provides this return code, at least up to its release tag
v2025.01 [1].

Without this change, OP-TEE fails to communicate with U-Boot RPMB
RPC service since RPMB probe capability was merged in OP-TEE
(Fixes: tag below).

drivers: clk: sam: rename the sama7g5 UTMI clocks for USB PHY

The UTMI clocks for USB PHY are handled in OP-TEE due to they are
controlled by the registers from RSTC (reset controller) which is
always-secured.
SCMI "reset domain management protocol" makes it prossible to handle the
resets from the kernel running in normal world. So the code in kernel for
these clocks need to be enabled. Here renaming the clocks to avoid
registering them failed from the kernel.

core: arm: guest ID test for notif and VM creation

Block normal world from calling OPTEE_SMC_VM_CREATED with reserved
hypervisor client-id (0) as VMID parameter.

Normal world calls OPTEE_SMC_VM_CREATED with guest VMID in a1 and
HYP_CLNT_ID in a7. This eventually leads to copying of __data_start
to __data_end from the default partition to the guest's MMU partition.
Everything goes well until normal world passes HYP_CLNT_ID into a1 which
goes unchecked in OPTEE. When the "second VM" is created from normal
world, the first VM's MMU partition's __data_start is copied into
the new VM's MMU partition which eventually breaks the bpool freelist
pointers.

This can deliberately be used by normal world to put OP-TEE into panic.

Set guest ID when NOTIF_EVENT_STARTED is called preventing assetion
failure in get_notif_data().

core: arm: pass guest ID to SMC_ENABLE_ASYNC_NOTIF

notif_deliver_atomic_event() expects guest_id which
is used to retrieve struct guest_partition* from
virt_get_guest(). The guest_id passed is static (0),
which causes trouble when OPTEE_SMC_ENABLE_ASYNC_NOTIF
comes from a guest. When this happens, virt_get_guest()
returns NULL which fails the assertion in get_notif_data()
which exclusively checks for CONFIG_NS_VIRTUALIZATION.
