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

In commit # 0a3e4e94d137 ("platform/x86/intel/ifs: Add SBAF test image
loading support"), the documentation for "Structural Based Functional
Test at Field (SBAF)" had an incomplete underline. This resulted in the
following build warning:

Documentation/arch/x86/ifs:2: drivers/platform/x86/intel/ifs/ifs.h:131: WARNING: Title underline too short.

Fix it by extending the dotted lines to match the length of the title.

Intel-SIG: commit 1e701372d7ac platform/x86/intel/ifs: Fix SBAF title underline length
Backport to support IFS(In Field Scan) SBAF(Structural Based Functional Test at Field)
