Akinobu Mita 5da444aae5 sparc: fix format string argument for prom_printf() 
prom_printf() takes printf style arguments.  Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().

This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.
