device/oprom/yabel/io: use __fallthrough instead of comment
Unlike gcc, a clang build will fail when only a comment is used to
indicate that the fallthough is intended. To fix the clang build, use
__fallthrough instead. This will fix the build errors introduced by
commit f45c7671d9ed ("Set x86_64 as supported architecture for clang")
that enabled clang builds for a case that uses yabel to run the VBIOS.
