unicore32-softmmu: Add coprocessor 0(sysctrl) and 1(ocd) instruction support
Coprocessor 0 is system control coprocessor, and we need get/set its contents.
Also, all cache/tlb ops shoule be implemented here, but just ignored with no harm.
Coprocessor 1 is OCD (on-chip-debugger), which is used for faked console,
so we could output chars to this console without graphic card.
TODO: curses display should be added lator for screen output.
