refactor(cm): make SVE and SME build dependencies logical

Currently, enabling SME forces SVE off. However, the SME enablement
requires SVE to be enabled, which is reflected in code. This is the
opposite of what the build flags require.

Further, the few platforms that enable SME also explicitly enable SVE.
Their platform.mk runs after the defaults.mk file so this override never
materializes. As a result, the override is only present on the
commandline.

Change it to something sensible where if SME is on then code can rely on
SVE being on too. Do this with a check in the Makefile as it is the more
widely used pattern. This maintains all valid use cases but subtly
changes corner cases no one uses at the moment to require a slightly
different combination of flags.

feat(sme): enable SME2 functionality for NS world

FEAT_SME2 is an extension of FEAT_SME and an optional feature
from v9.2. Its an extension of SME, wherein it not only
processes matrix operations efficiently, but also provides
outer-product instructions to accelerate matrix operations.
It affords instructions for multi-vector operations.
Further, it adds an 512 bit architectural register ZT0.

This patch implements all the changes introduced with FEAT_SME2
to ensure that the instructions are allowed to access ZT0
register from Non-secure lower exception levels.

Additionally, it adds support to ensure FEAT_SME2 is aligned
with the existing FEATURE DETECTION mechanism, and documented.

feat(allwinner): add support for Allwinner T507 SoC

The Allwinner T507 SoC is using the same die as the H616, but in a
different package. On top of this, there is at least one different die
revision out there, which uses a different CPU cluster control block.
The same die revision has been spotted in some, but not all, H313 SoCs.

Apart from that IP block, the rest of the SoC seems the same, so we can
support them using the existing H616 port. The die revision can be
auto-detected, so there is no extra build option or knowledge needed.

Provide the deviating CPU power up/down sequence for the die variant.
The new IP block uses per-core instead of per-cluster registers, but
follows the same pattern otherwise.

Since the CPU ops code is shared among all Allwinner SoCs, we need to
dummy-define the new register names for the older SoCs. The actual new
code is guarded by a predicate function, that is hard coded to return
true on the other SoCs. Since this is a static inline function in a
header file, the compiler will optimise away the unneeded branch there,
so the generated code for the other SoCs stays the same.

This patch introduces the 'pwr_domain_off_early' hook for
platforms wanting to perform housekeeping steps before the
PSCI framework starts the CPU power off sequence. Platforms
might also want to use ths opportunity to ensure that the
CPU off sequence can proceed.

The PSCI framework expects a return code of PSCI_E_DENIED,
if the platform wants to halt the CPU off sequence.
