[PATCH 1/8] SVM: move feature detection to hardware setup code

["Joerg Roedel" <joerg.roedel@amd.com>]

By moving the SVM feature detection from the each_cpu code to the hardware
setup code it runs only once. As an additional advance the feature check is now
available earlier in the module setup process.
