Evgeniy Paltsev fbc9fbf92f ARC: save/restore accumulator registers on all ARCv2 HS CPUs by default
Accumulator registers (ACCL, ACCH) are used on HS CPUs not only
in case of FPU usage but also in case of MPY usage. We enable MPY
for all ARCv2 HS in commit
18a24c3f6 ARC: gcc-m-cpu: use -mcpu=archs as a default for ARCv2 HS
but we didn't enable accumulator registers management.

Let's enable accumulator registers save/restore on all ARCv2 HS CPUs
by default.
