This reverts commit 0c57dfcc6c.
The functionality was supoosed to be used by a later patch in the
series that never landed [1]. Drop it.
NOTE: part of functionality was already reverted by commit
39d0be8743 ("serial: kgdb_nmi: Remove unused knock code"). Also note
that this revert is not a clean revert given code changes that have
happened in the meantime.
It's obvious that nobody is using this code since the two exposed
functions (kgdb_register_nmi_console() and
kgdb_unregister_nmi_console()) are both no-ops if
"arch_kgdb_ops.enable_nmi" is not defined. No architectures define it.
