x86: Calgary: Convert detect_calgary() to use iommu_init hook

Browse Source 
This changes detect_calgary() to set init_calgary() to
iommu_init hook if detect_calgary() finds the Calgary IOMMU.

We can kill the code to check if we found the IOMMU in
init_calgary() since detect_calgary() sets init_calgary() only
when it found the IOMMU.
