We want to make sure that CPU topology information given to QEMU would
be provided to the operating system. So we use SMC call to ask TF-A for
amount of sockets, clusters, cores and threads set in QEMU config.
The TF-A part is already merged:

Changes in v5:
- added support for cache sizes on cores with FEAT_CCIDX (Neoverse V1+)
- Link to v4: https://openfw.io/edk2-devel/20240710-acpi65-v4-0-bc32224e4be4@linaro.org
Changes in v4:
- renamed all *Index variables to *Offset ones for clarity
- renamed static CpuId/CacheId variable to mCpuId/mCacheId
- moved above variables outside of pragma pack
- moved all variables definitions to start of functions
- added reading cpu cache size from CCIDR registers
- changed wording in SbsaHardwareInfoLib header
- changed wording in 3rd patch commit message
- Link to v3: https://openfw.io/edk2-devel/20240709-acpi65-v3-0-ee93ba536fcf@linaro.org
Changes in v3:
- split ACPI 6.5 changes into separate patch
- moved adding cores/threads to separate function
- fixed cache offsets
- Link to v2: https://openfw.io/edk2-devel/20240702-acpi65-v2-0-3cb18a892221@linaro.org/T/#t
Changes in v2 (Marcin Juszkiewicz):
- use ACPI 6.5 structures (instead of 6.3)
- add patch to move cache data to cores (instead of clusters)
- this is for future MPAM support
- reformatted sources using uncrustify
- changed debug output to allow singular values (s/are/:/)

Provide functions to check for CPU topology information:
- the number of sockets on sbsa-ref platform.
- the number of clusters in one socket.
- the number of cores in one cluster.
- the number of threads in one core.
As SMC calls can return up to 4 return values, the number of sockets,
clusters and cores are read from TF-A using platform specific SMC call.
Number of threads is caluculated using the cpu count and the number of
sockets, clusters and cores.

To align the CPU topology information recognized by the operating system
with the CPU topology information configured by QEMU, we need to make
use of the CPU topology information to create complex PPTT tables
setups.
We can get the CPU topology information via SMC.

During Linaro Connect MAD24 I was asked to move cache information from
being 'per cluster' to be 'per core'. This is a move for implementing
MPAM support.
So topology moves from:
Socket -> Clusters -> Cores + Caches -> Threads (if exist)
to:
Socket -> Clusters -> Cores -> Caches + Threads (if exist)
Cache sizes are still 32+32+512KB (L1d, L1i, L2) as QEMU does not
implement them at all so we can tell whatever.

Function AddPpttTable() adding PPTT got too long. This change moves part
of it into helper function AddCoresToPpttTable() which takes care of
generating entries for Core and below (Cache, Thread).

We were exporting fake cpu cache values instead of reading them from
CCSIDR registers.
This change gets rid of fake values in favour of existing ones.
Based on Ampere platform core. Added support for cpus with FEAT_CCIDX
(Neoverse-V1 and above).
