NPS customers are no longer doing active development, as evident from
rand config build failures reported in recent times, so drop support
for NPS platform.

ARC: add support for DSP-enabled userspace applications2020-03-16T17:30:49+00:00Eugeniy PaltsevEugeniy.Paltsev@synopsys.com2020-03-05T20:02:51+00:00urn:sha1:7321e2ea0d6aece516a9c0827028ecda2ccaeae9
To be able to run DSP-enabled userspace applications we need to
save and restore following DSP-related registers:
At IRQ/exception entry/exit:
* DSP_CTRL (save it and reset to value suitable for kernel)
* ACC0_LO, ACC0_HI (we already save them as r58, r59 pair)
At context switch:
* ACC0_GLO, ACC0_GHI
* DSP_BFLY0, DSP_FFT_CTRL

save EFLAGS, and GPA1 auxiliary registers during context switch,
since they may be changed by the new task in kernel mode, while using atomic
ops e.g. cmpxchg.
