Workaround for Cortex A76 erratum 1800710

Cortex A76 erratum 1800710 is a Cat B erratum, present in older
revisions of the Cortex A76 processor core. The workaround is to
set a bit in the ECTLR_EL1 system register, which disables allocation
of splintered pages in the L2 TLB.

TF-A GIC driver: Add barrier before eoi

It is desired to have the peripheral writes completed to clear the
interrupt condition and de-assert the interrupt request to GIC before
EOI write. Failing which spurious interrupt will occurred.

A barrier is needed to ensure peripheral register write transfers are
complete before EOI is done.

GICv2 memory mapped DEVICE nGnR(n)E writes are ordered from core point
of view. However these writes may pass over different interconnects,
bridges, buffers leaving some rare chances for the actual write to
complete out of order.

GICv3 ICC EOI system register writes have no ordering against nGnR(n)E
memory writes as they are over different interfaces.

Hence a dsb can ensure from core no writes are issued before the previous
writes are *complete*.

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
or fastcall SMCCC invocation.

SMT description in this implementation is based on the OP-TEE
project [1] itself based in the SCP-firmware implementation [2].

drivers/scmi-msg: driver for processing scmi messages

This change introduces drivers to allow a platform to create a basic
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.

The SCMI message implementation is derived from the OP-TEE project [2]
itself based on the SCP-firmware implementation [3] of the SCMI protocol
server side.
