arc: Use accl_operand predicate for fma instructions.
With the refurbish of ARC600' accumulator support, the mlo_operand
doesn't reflect the proper low accumulator register for the newer
ARCv2 accumulator register used by the fma instructions. Hence,
replace it with accl_operand predicate.

* config/arc/arc.md (fmasf4_fpu): Use accl_operand predicate.
(fnmasf4_fpu): Likewise.
