ci: add cv200_neo + av100_neo qemu-boot matrix rows (closes #2123 from firmware) (#181)

Now that the firmware nightly publishes openipc.hi3516cv200-nor-neo.tgz
and openipc.hi3516av100-nor-neo.tgz (after OpenIPC/firmware#2124 added
both boards to the firmware build.yml matrix), wire two new rows into
the qemu-boot job.

Each row downloads the appropriate -nor-neo.tgz from the latest
firmware release and runs the same boot smoke as the lite rows.

Local pre-merge validation against the published nightly tarballs:

  hi3516cv200_neo:
    [PASS] login (openipc-hi3516cv200 login:)
    [PASS] IP (10.0.2.15 via SLIRP DHCP)
    [PASS] ping 10.0.2.2

  hi3516av100_neo:
    [PASS] login (openipc-hi3516av100 login:)
    [PASS] IP (10.0.2.15 via SLIRP DHCP)
    [PASS] ping 10.0.2.2

Both also clean on Oops/panic/BUG/Call Trace patterns.

Row mechanics — new optional `variant:` field:

  - Defaults to lite. Rows that don't set it stay byte-equivalent
    (download URL becomes openipc.X-nor-lite.tgz, row name unchanged).
  - When `variant: neo`:
      * row name becomes "QEMU boot (<machine>_neo)"
      * download URL becomes openipc.<machine>-nor-neo.tgz
      * upload-artifact name becomes "qemu-boot-<machine>_neo"

Both new rows are real gates (no allow-failure: true). load_hisilicon
on neo doesn't load HiSi blobs (kernel-version path mismatch — separate
firmware follow-up to teach it the /lib/modules/7.0 path), so neither
row sets min_modules; the assertion is "login reached + no error
patterns". That's what the local DoD test exercises and what the CI
will exercise.
