openrisc: fix initial preempt state for secondary cpu tasks
During SMP testing we were getting the below warning after booting the
secondary cpu:
[ 0.060000] BUG: scheduling while atomic: swapper/1/0/0x00000000
This change follows similar patterns from other architectures to start
the schduler with preempt disabled.
