core: console: Allow setting logging verbosity during runtime

The default console can be disabled at runtime for power management. Any
prints after boot from OP-TEE could cause a bus data abort if the UART has
been disabled. Add an option to change the log level after boot has
completed which can be used to disable the console log.

core: arm: refactor RD-1AE and RD-Aspen into automotive_rd flavors

This change moves RD-1AE and RD-Aspen under a single
automotive_rd platform with per-flavor configuration.

Key updates:
- Introduce plat-automotive_rd/ with shared main.c,
platform_config.h and Makefiles.
- Define RD-1AE and RD-Aspen are selected
via PLATFORM_FLAVOR rd1ae or rdaspen.
- Merge flavor settings (UART/GIC/DRAM/topology)
into platform_config.h and conf.mk files.
- Use default get_core_pos_mpidr() by setting appropriate
CFG_CORE_CLUSTER_SHIFT / CFG_CORE_THREAD_SHIFT for rdaspen,
eliminating custom assembly where not required.

Benefits:
- Consistent with OP-TEE’s platform/variant framework.
- Reduces code duplication between RD-1AE and RD-Aspen.
- Simplifies adding new automotive reference design flavors
in the future.

Usage:
- Set PLATFORM=automotive_rd
- Set PLATFORM_FLAVOR to rdaspen or rd1ae

core: arm: stmm_sp: return FFA_NOT_SUPPORTED for undefined FFA functions

edk2's patch ("ArmFfaLib: Add Rx/Tx support for Stmm secure partition") [0]
added Rx/Tx buffer mapping support to ArmFfaStandaloneMm(Core)Lib.

However, stmm_sp does not require Rx/Tx buffer mapping and
its SVC handler is lightweight. Therefore, when it receives
an undefined FFA function, it is sufficient to return FFA_NOT_SUPPORTED to
StandaloneMm instead of panicking.

This also aligns with the FF-A specification, which requires returning
FFA_NOT_SUPPORTED when an unimplemented function ID is received.

If StandaloneMm fails to initialize, it will return FFA_ERROR.
In this case, there is no way to keep the stmm_sp TA alive,
so panic is called.
Otherwise, StandaloneMm will return with DIRECT_MSG_RESP.

core: riscv: add initial RPMI/MPXY integration support

This commit introduces infrastructure to support RPMI communication via
the SBI MPXY extension. MPXY allows supervisor software to send and
receive RPMI messages through M-mode firmware acting as a proxy.

Functions added by this commit are sufficient to implement the
RequestForward service group.

Support for asynchronous events, notifications, and MSI-based message
delivery will be added in future commits.

core: riscv: implement MPXY SBI extension

Introduce support for the MPXY SBI extension (EID #0x4D505859),
which enables supervisor software to exchange messages through
an abstract SBI interface decoupled from any specific protocol.

MPXY allows setting up per-hart shared memory for transferring
messages between the supervisor and an SBI implementation.
It serves as a generic backend to build messaging clients,
while being agnostic of message protocol semantics.

This step provides the foundation for future inter-domain
message exchange.

core: tpm: fix TPM log address parsing to use full 64-bit address

Remove ARM32-specific address parsing that only used the lower 32 bits
of the TPM event log address. ARM32 systems can have 64-bit physical
addresses, so the full 64-bit address from the device tree property
should be parsed regardless of architecture.

The fix ensures both ARM32 and ARM64 architectures use the same
64-bit address construction: (property[0] << 32) | property[1],
preventing potential address truncation issues on ARM32 systems
with 64-bit physical address spaces.

core: tpm: fix TPM log area zeroing condition to avoid manifest DT write fault

Change the condition for zeroing TPM event log address in device tree
from CFG_CORE_SEL1_SPMC to CFG_CORE_FFA. When CFG_CORE_FFA is enabled,
the device tree comes from the manifest DT which is mapped as read-only,
not from the external device tree. Attempting to zero the
tpm_event_log_addr property in the manifest DT would cause a write
permission fault exception.

The fix prevents this fault by ensuring the zeroing operation only occurs
when using the external device tree (CFG_CORE_FFA=n), where write access
is permitted.
