Eugeniy Paltsev 61c151693b ARC: ARCv2: handle DSP presence in HW
In case of DSP extension presence in HW some instructions
(related to integer multiply, multiply-accumulate, and divide
operation) executes on this DSP execution unit. So their
execution will depend on dsp configuration register (DSP_CTRL)
As we want these instructions to execute the same way regardless
of DSP presence we need to set DSP_CTRL properly.

NOTE:
we do the same adjustments in Linux kernel, see in kernel tree:
