[IA64] FPH enabling + cleanup

Move contents of switch_to macro from xensystem.h to context_switch function.
Initialize FPU on all processors. FPH is always enabled in Xen.
Speed up context-switch (a little bit!) by not enabling/disabling FPH.
Cleanup (unused function/variablesi/fields, debug printf...)
vmx_ia64_switch_to removed (was unused).
