Since now the generic console_t structure holds the UART base address as
well, let's use that generic location and drop the UART driver specific
data structure at all.

There are two different implementations of Secure Partition
management in TF-A. One is based on the "Management Mode" (MM)
design, the other is based on the Secure Partition Client Interface
(SPCI) specification. Currently there is a dependency between their
build flags that shouldn't exist, making further development
harder than it should be. This patch removes that
dependency, making the two flags function independently.

Before: ENABLE_SPM=1 is required for using either implementation.
        By default, the SPCI-based implementation is enabled and
        this is overridden if SPM_MM=1.

After: ENABLE_SPM=1 enables the SPCI-based implementation.
       SPM_MM=1 enables the MM-based implementation.
       The two build flags are mutually exclusive.

Note that the name of the ENABLE_SPM flag remains a bit
ambiguous - this will be improved in a subsequent patch. For this
patch the intention was to leave the name as-is so that it is
easier to track the changes that were made.

Enable the SCMI protocol support in SynQuacer platform.
Aside from power domain, system power and apcore management protocol,
this commit adds the vendor specific protocol(0x80).
This vendor specific protocol is used to get the dram mapping information
from SCP.

The SPM implementation based on MM is going to be kept for the
foreseeable future.

Enable the deprecated SPM framework for the SynQuacer platform.
It involves creating a memory layout in secure DRAM, and wiring
up the SPM infrastructure so that the secure partition payload
that is loaded into this region by the SCP firmware is dispatched
appropriately.

The logic that initializes the BL32 entry point data structure
should only be executed if we are in fact loading OP-TEE, and
not if BL32_BASE is set for other reasons (i.e., when enabling
SPM)

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

BL31 runs from SRAM which is a non-coherent memory on synquacer. So
enable MMU with SRAM memory marked as Non-Cacheable and mark page tables
kept on SRAM as Non-Cacheable via XLAT_TABLE_NC flag. Also add page tables
