amd xsave: 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.
