ARCv2: Use the default irq priority for idle sleep 

Although kernel doesn't support the multiple IRQ priority levels provided
by HS38x core intc yet, ensure that the default prio value is used
anyways by relevant code.

SLEEP insn needs to be provided the IRQ priority level which can
interrupt it. This needs to be the default level which maynot
necessarily be 0 as assumed by current code.

This change allows a kernel with ARCV2_IRQ_DEF_PRIO = 1 to boot fine.
