Shift the ITS processor ID after reading it.

Browse Source 
When using the processor ID value we mask off the low and high bits that
should be zero. Unfortunatly we don't shift the ID value so it won't be
affected. Add the shift when reading the ID as this will need to align
with the address based target value.
