mips: optimize write code for speed
All the writes are done by the new function mips32_pracc_write_mem_generic().
The code is similar to the read generic code.
The reuse of register 15 as memory base address saves 3 pracc accesses.
The first write takes 13(12) pracc accesses and for additional writes 3(2).
Loading miniprograms should take 25% less time and loading fastdata transfer
handler code should be over 2x faster.
