sim: common: change sim_{fetch,store}_register helpers to use void* buffers

Browse Source 
When reading/writing arbitrary data to the system's memory, the unsigned
char pointer type doesn't make that much sense.  Switch it to void so we
align a bit with standard C library read/write functions, and to avoid
having to sprinkle casts everywhere.
