armv8: fsl-layerscape: Add support of disabling core prefetch

Instruction prefetch feature is by default enabled during core
release. This patch add support of disabling instruction prefetch
by setting core mask in PPA. Here each core mask bit represents a
core and prefetch is disabled at the time of core release.
