Diana Craciun 7fef436295 powerpc/fsl: Flush the branch predictor at each kernel entry (32 bit) ...

In order to protect against speculation attacks on
indirect branches, the branch predictor is flushed at
kernel entry to protect for the following situations:
- userspace process attacking another userspace process
- userspace process attacking the kernel
Basically when the privillege level change (i.e.the kernel
is entered), the branch predictor state is flushed.
