target/mips: Add Loongson-3 CPU definition
Loongson-3 CPU family include Loongson-3A R1/R2/R3/R4 and Loongson-3B
R1/R2. Loongson-3A R1 is the oldest and its ISA is the smallest, while
Loongson-3A R4 is the newest and its ISA is almost the superset of all
others. To reduce complexity, we just define two CPU types:
1) "Loongson-3A1000" CPU which is corresponding to Loongson-3A R1. It is
suitable for TCG because Loongson-3A R1 has fewest ASE.
2) "Loongson-3A4000" CPU which is corresponding to Loongson-3A R4. It is
suitable for KVM because Loongson-3A R4 has the VZ ASE.
Loongson-3A has CONFIG6 and CONFIG7, so add their bit-fields as well.
[AM: Rearranged insn_flags, added comments, renamed lmi_helper.c,
improved commit message, fixed checkpatch warnings]
