MIPS: Loongson: Add Loongson-3A R2 basic support
Loongson-3 CPU family: Code-name Brand-name PRId Loongson-3A R1 Loongson-3A1000 0x6305 Loongson-3A R2 Loongson-3A2000 0x6308 Loongson-3B R1 Loongson-3B1000 0x6306 Loongson-3B R2 Loongson-3B1500 0x6307 Features of R2 revision of Loongson-3A: - Primary cache includes I-Cache, D-Cache and V-Cache (Victim Cache). - I-Cache, D-Cache and V-Cache are 16-way set-associative, linesize is 64 bytes. - 64 entries of VTLB (classic TLB), 1024 entries of FTLB (8-way set-associative). - Supports DSP/DSPv2 instructions, UserLocal register and Read-Inhibit/ Execute-Inhibit.
