sparc: Remove BKL from apc
commit ab772027 (sparc: arch/sparc/kernel/apc.c to unlocked_ioctl)
added lock/unlock_kernel() to the apc ioctl code.
The code needs no serialization at all. Neither put/get_user nor the
read/write access to the sbus devices require it. Remove BKL.
cycle_kernel_lock() was added during the big BKL pushdown. It should
ensure the serializiation against driver init code. In this case there
is nothing to serialize. Remove it as well.
