MIPS: Loongson: Remove out-of-date board-specific kgdb source code
Since the re-implementation of kgdb by commit 8854700115ecf8aa6f087aa915b7b6cf18090d39 the platform-specific version has become superfluous, remove it. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
