Move xsave initialization code to a common place This patch moves xsave/xrstor code to CPU common file. First of all, it prepares xsave/xrstor support for AMD CPUs. Secondly, Xen would crash on __context_switch() without this patch on xsave-capable AMD CPUs. The crash was due to cpu_has_xsave reports true in domain.c while xsave space wasn't initialized.
