MIPS: Remove old core dump functions
Since the core dumper now uses regsets, the old core dump functions are now unused. Remove them. Signed-off-by: Alex Smith <alex@alex-smith.me.uk> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/7456/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
