The resctrl selftest currently exhibits several failures on Hygon CPUs
due to missing vendor detection and edge-case handling specific to
Hygon's architecture.

This patch series addresses three distinct issues:
1. Missing CPU vendor detection, causing the test to fail with
   "# Can not get vendor info..." on Hygon CPUs.
2. A division-by-zero crash in SNC detection on Hygon CPUs.
3. Incorrect handling of non-contiguous CBM support on Hygon CPUs.

These changes enable resctrl selftest to run successfully on
Hygon CPUs that support Platform QoS features.

  selftests/resctrl: Add CPU vendor detection for Hygon
  selftests/resctrl: Fix a division by zero error on Hygon
  selftests/resctrl: Fix non-contiguous CBM check for Hygon
