[PATCH v4 0/3] Add support for Fujitsu A64FX processor

[Shuuichirou Ishii <ishii.shuuichir@fujitsu.com>]

This is the v4 patch series.

v4:
The following changes have been made to match the SVE specification of
the A64FX processor.
- Implemented internally only the vector lengths of 128, 256, and 512 bit
  supported by the A64FX processor.
- Removed sve and sve-max-vq properties due to the above changes, and
  fixed them so that no explicit options can be specified.

v3:
When we created the v2 patch series, we based it on the v1 patch series
that had not been merged into the upstream, so we created the v3 patch
series as a patch series that can be applied independently.

v2:
No features have been added or removed from the v1 patch series. Removal
of unused definitions that were added in excess, and consolidation of
patches for the purpose of functional consistency.

For patch 1, Implemented Identification registers for A64FX processor.
HPC extension registers will be implemented in the future.
For SVE, the A64FX processor supports only 128,256 and 512bit vector lengths.

For patch 2, A64FX processor can now be used by specifying the -cpu
a64fx option when the -macine virt option is specified.

For patch 3, added A64FX processor related tests.
