selftests: ifs: verify IFS ARRAY BIST functionality 

mainline inclusion
from mainline-v6.11-rc1
commit bb408dae9e73803eab8a648115d6c4a1bca4dba3
category: feature
bugzilla: https://gitee.com/openeuler/intel-kernel/issues/IASVRQ
CVE: N/A
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bb408dae9e73803eab8a648115d6c4a1bca4dba3



-------------------------------------

There are two selftest scenarios for ARRAY BIST(Board Integrated System
Test) tests:

1. Perform IFS ARRAY BIST tests once on each CPU.
2. Perform IFS ARRAY BIST tests on a random CPU with 3 rounds.

These are not meant to be exhaustive, but are some minimal tests for
for checking IFS ARRAY BIST.
