Log:
  ofw: ofw_reg_to_paddr: Use a 256 static array for the cell
  
  Some hardware needs more than 32, bump this value.
  
  We cannot use the _alloc for of getencprop as this function is called
  too early in the boot before pmap is initialized and we only have
  2k of stack when cninit is called.
