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.
