plat-sam: add timer clock driver

Add support for the TCB block that are present on the samad2. This
series add support for the TCB as a time source and register it using
REGISTER_TIME_SOURCE(). Moreover, on Linux, the tick is done using the
TCB since the sama5d2 does not have the ARM architected timers. Since
the time source used for the tick clocksource is probed early in the
boot process, the SCMI clock support which uses a platform driver is
not yet probed and thus the TCB can't be probe properly. To workaround
that problem, this driver enables the TCB clocks and the Linux
device-tree is modified to use "fixed-clock" clock instead of the TCB
SCMI ones.

drivers: scmi-msg: add SCMI MSG message protocol

Implements MSG header protocol to handle SCMI messages. MSG header
protocol was introduced in Linux kernel v5.15 [1]. It relies on normal
cached shared memory buffer using a 32bit header followed by the SCMI
message payload.

To support this message interface, the SCMI PTA defines a new capability
and a new command. Capability PTA_SCMI_CAPS_MSG_HEADER allows client and
service to negotiate the desired transport configuration. Command
PTA_SCMI_CMD_PROCESS_MSG_CHANNEL allows client to request processing
of a message sent based on that message exchange protocol.

Platforms shall enable configuration switch CFG_SCMI_MSG_SHM_MSG to have
their SCMI service supporting that communication protocol.

Changes implementation channel_to_smt_hdr() of SMT message management
in scmi-msg driver to support being called with invalid channel ID
to relax implementation. On contrary, scmi_smt_init_agent_channel()
is expected to be called only for valid SMT channels.

By the way, with this change, scmi_entry_smt() read SMT header status
from shared memory after channel in successfully claimed, not before.
The change does not affect the communication and makes the implementation
more consistent. For consistency, I also rename local variables chan to
channel to be more explicit.
