[PATCH v2 2/2] MIPS p8700 doesn't have vector extension and added the dummies reserva...

The RISC-V backend requires all types to map to a reservation in the
scheduler model.  This adds types to a dummy reservation for all the
types not currently handled by the p8700 model.

gcc/
	* config/riscv/mips-p8700.md (mips_p8700_dummies): New
	reservation.
	(mips_p8700_unknown): Reservation for all the dummies.
