Actually, it works fine without including hvm/params.h in xen_common.h
because xen_common.h includes xenctrl.h which includes hvm/params.h.

So I think instead I'll remove all includes of params.h, because
HVM_PARAM_* are parameters for xc_hvm_param_{get,set}, which is in a
library and not an interface with a guest. Including xenctrl.h should be
enough.
