Gabe Black 93b3176d4e Fixed the priv instruction format. 
src/arch/sparc/isa/formats/priv.isa:
    Fix the priv format so that it uses isa_parser operands rather than accessing the registers directly in checkCode. Also, the expressions needed to be negated.
src/arch/sparc/isa/operands.isa:
    Added an Hpstate operand, and adjusted the numbering.
