lib/Kconfig.debug: adjust hard-lockup related Kconfig options
The main option should not appear in the resulting .config when the
dependencies aren't met (i.e. use "depends on" rather than directly
setting the default from the combined dependency values).
The sub-options should depend on the main option rather than a more
generic higher level one.

Say Y here to enable the kernel to panic on "hard lockups",
which are bugs that cause the kernel to loop in kernel
