[PATCH v2 07/11] ARC: [plat-eznps] disabled stall counter due to a HW bug

[Noam Camus]

From: Noam Camus <noamca@xxxxxxxxxxxx>

This counter represents threshold for consecutive stall that which
trigger HW threads scheduling.
When this feature is enabled low values of this counter cause
downgrade in performance and in the worst case even a livelock.

Remove those couple of lines and resort to HW reset value i.e.
this feature is disabled (.sten field equals 0).
