[PATCH] drm/amd/display: remove check for nonexistent CONFIG_HAVE_KGDB

[Ethan Nelson-Moore <enelsonmoore@gmail.com>]

drivers/gpu/drm/amd/display/dc/sspl/spl_debug.h checks for
CONFIG_HAVE_KGDB or CONFIG_KGDB to determine whether to call
kgdb_breakpoint(). CONFIG_HAVE_KGDB has never existed in the kernel.
Remove the check for it and retain only the correct check for
CONFIG_KGDB.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
