MIPS patches queue

Hardware emulation:
 - Generate FDT blob for Boston machine (Jiaxun)
 - VIA chipset cleanups (Zoltan)
 
 TCG:
 - Use tcg_constant() in Compact branch and MSA opcodes
 - Restrict nanoMIPS DSP MULT[U] opcode accumulator to Rel6
 - Fix DEXTRV_S.H DSP opcode
 - Remove unused TCG temporary for some DSP opcodes
