Enable the Corstone‑1000 Cortex‑A320 variant by:
- Introduce `machine/include/corstone1000-a320.inc` to configure the
default Ethos‑U MAC count when `cortexa320` is in MACHINE_FEATURES,
and allow override via `ETHOSU_NUM_MACS`.
- Add a KAS profile at `kas/corstone1000-a320.yml` for Cortex‑A320
FVP-based builds.
- Extend corstone1000.inc to detect MACHINE_FEATURES (cortexa320) and
pull in the matching tune-<core>.inc (default still Cortex-A35).
- Add the `meta-ethos` layer as a dependency of `meta-arm-bsp` for
Cortex‑A320 builds and define a new KMachine override to pull in
the Ethos‑U driver recipe.
- In `conf/machine/corstone1000-fvp.conf`, inspect `MACHINE_FEATURES`
and set `FVP_EXE` to `FVP_Corstone-1000_with_Cortex-A320` when
`cortexa320` is enabled, otherwise fall back to `FVP_Corstone-1000`.
- In `recipes-devtools/fvp/fvp-corstone1000.bb`, add a
`SRC_URI:cortexa320` entry (with checksums) for the Cortex‑A320 FVP
build archive.
- Disable the rootfs CPIO file compression so it is not compressed
twice when bundled with the kernel
