xen/arm: Make AFFINITY_MASK generate correct mask for level3

The original affinity shift bits algorithm in AFFINITY_MASK is buggy,
it could not generate correct affinity shift bits of level3.
The macro MPIDR_LEVEL_SHIFT can calculate level3 affinity shift bits
correctly. We use this macro in AFFINITY_MASK to generate correct
mask for level3.
