drivers/scmi-msg: smt entry points for incoming messages

This change implements SCMI channels for reading a SCMI message from a
shared memory and call the SCMI message drivers to route the message
to the target platform services.

SMT refers to the shared memory management protocol which is used
to get/put message/response in shared memory. SMT is a 28byte header
stating shared memory state and exchanged protocol data.

The processing entry for a SCMI message can be a secure interrupt
(CFG_SCMI_MSG_SMT_INTERRUPT_ENTRY=y), and fastcall SMC
(CFG_SCMI_MSG_SMT_FASTCALL_ENTRY=y) or a threaded execution
context entry (CFG_SCMI_MSG_SMT_THREAD_ENTRY=y).

SMT description in this implementation is based on the SCP-firmware
implementation [1].

drivers/scmi-msg: driver for processing scmi messages

This change introduces drivers to allow a platform to create a SCMI
service and register handlers for client request (SCMI agent) on
system resources. This is the first piece of the drivers: an entry
function, the SCMI base protocol support and helpers for create
the response message.

With this change, scmi_process_message() is the entry function to
process an incoming SCMI message. The function expect the message
is already copied from shared memory into secure memory. The message
structure stores message reference and output buffer reference where
response message shall be stored.

scmi_process_message() calls the SCMI protocol driver according to
the protocol ID in the message. The SCMI protocol driver will call
defined platform handlers according to the message content.

This change introduces only the SCMI base protocol as defined in
SCMI specification v2.0 [1]. Not all the messages defined
in the specification are supported.

SCMI resource in this implementation are dumped or inspired by the
SCP-firmware implementation [2] of the SCMI protocol, server side.

Remove '.section .text.<name>' and use function macros instead

Assembler functions are normally defined using the FUNC/LOCAL_FUNC
macros from <asm.S>. The macros takes care of several things, including
putting the function in a specific section for later garbage collection
by the linker (--gc-sections).

A few files do not follow this convention, let's fix them. Two
functions in ghash-ce-core_a64.S (pmull_gcm_load_round_keys() and
pmull_gcm_aes_sub()) totally lack a .section directive, which I think
is a mistake. Fix them at the same time.

No functional change is expected.
