hw/ppc: Fix iothread locking in the 405 code
When using u-boot as firmware with the taihu board, QEMU aborts with
this assertion:
ERROR:../accel/tcg/tcg-accel-ops.c:79:tcg_handle_interrupt: assertion failed:
(qemu_mutex_iothread_locked())
Running QEMU with "-d in_asm" shows that the crash happens when writing
to SPR 0x3f2, so we are missing to lock the iothread in the code path
here.
