selftests: ifs: verify test interfaces are created by the driver 

mainline inclusion
from mainline-v6.11-rc1
commit 8e51106d02d32cd83807fa56c602020c2309ace0
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=8e51106d02d32cd83807fa56c602020c2309ace0



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

IFS (In Field Scan) driver exposes its functionality via sysfs interfaces.
Applications prepare and exercise the tests by interacting with the
aforementioned sysfs files.

Verify that the necessary sysfs entries are created after loading the IFS
driver.

Initialize test variables needed for building subsequent kself-test cases.

Intel-SIG: commit 8e51106d02d3 selftests: ifs: verify test interfaces are created by the driver
Backport to support IFS(In Field Scan) SBAF(Structural Based Functional Test at Field)
