Add -march=4ks[cd] to MIPS_ISA_LEVEL_SPEC

- Subject: Add -march=4ks[cd] to MIPS_ISA_LEVEL_SPEC
When reviewing the -march=4ks[cd] patch, I'd forgotten that
MIPS_ISA_LEVEL_SPEC also needs to be updated. Done with the
patch below. I also added a comment above mips_cpu_info_table
as a reminder (to myself as much as anyone).
Tested on mipsisa32r2-elfoabi. I checked that -march=4ksc now implies
-mips32 and that -march=4ksd now implies -mips32r2. Applied to trunk.

gcc/
* config/mips/mips.h (MIPS_ISA_LEVEL_SPEC): Handle -m4ksc and
-m4ksd.
* config/mips/mips.c (mips_cpu_info_table): Mention MIPS_ISA_LEVEL_SPEC
in the comment.
