[PATCH] LEON3 SMP: fix for first task switch

[Daniel Hellstrom]

_CPU_Context_switch_to_first_task_smp() branches to
done_flushing which requires o3 to be initalized with
"self per-CPU control", this adds initialization of
o3. This problem only affects SMP, see commit
f8ad6c6f7f8b591e were usage of o3 was intruduced.
