Watson Zeng 0da8ec70dc arch: arc: enable divide zero exception 
STATUS32.DZ(bit 13) is the EV_DivZero exception enable bit, and it's
not enabled by default. we need to set it explicitly to enable divide
zero exception on early boot and each thread's setup.

The DZ bit is ignored on write and read as zero when there is no
hardware division configured. So we can simply set DZ bit even if
there is no hardware division configured.
