hv:Clear up printf related definition

Browse Source 
In hypervisor, all the parameter and return value printf related are
unsigned int, this patch is used to fix the function definitions.

v1->v2:
  *Modify the return value of various functions, such as printf(),
   vprintf(), charout(), do_printf(), charmem, print_pow2(),
   print_decimal to void due to never used, no necessary to use,
   or has already returned by param.
  *Delete the impossible judgement of param->emit due to the type
   is unsigned.
