[gomp4] teach fortran to reject the device clause in acc routines

[Cesar Philippidis]

While porting the fortran acc routine changes from gomp4 to trunk, I
noticed that device was listed in the acc routine clause mask. That is
incorrect; it should be device_type not device. I fixed that problem in
the trunk patch submission. Here's the corresponding fix and test case
that I applied to gomp4.

As time permits, I'll add more test cases with invalid clause
combination for all of the constructs.

	gcc/fortran/
	* openmp.c (OACC_ROUTINE_CLAUSES): Remove OMP_CLAUSE_OACC_DEVICE
	from the clause mask.

	gcc/testsuite/
	* gfortran.dg/goacc/routine-6.f90: Ensure that the device clause is
	invalid with acc routines.
