Subject: [PATCH] powerpc/spufs: Remove MAX_USER_PRIO define

Current ppc64_defconfig fails with:

arch/powerpc/platforms/cell/spufs/sched.c:86:0: error: "MAX_USER_PRIO" redefined [-Werror]
cc1: all warnings being treated as errors

6b6350f1 introduced a generic MAX_USER_PRIO macro to sched/prio.h, which
is causing the conflit. Use that one instead of our own.

you can also use DEFAULT_PRIO from sched/prio.h instead of NORMAL_PRIO.
