[PATCH v1 1/5] xen/arm: field "flags" to cover all internal CDF_XXX

[Penny Zheng <Penny.Zheng@xxxxxxx>]

With more and more CDF_xxx internal flags in and to save the space, this
commit introduces a new field "flags" to store CDF_* internal flags
directly.

Another new CDF_xxx will be introduced in the next patch.
