[PATCH] x86/xen: select HIBERNATE_CALLBACKS more directly



From: Lukas Bulwahn <lukas.bulwahn@xxxxxxxxxx>

The config XEN_SAVE_RESTORE's only purpose is to select
HIBERNATE_CALLBACKS, when config XEN is set. The XEN config definition can
simply select HIBERNATE_CALLBACKS, though, and the definition of
XEN_SAVE_RESTORE can be dropped.

So, remove this indirection through XEN_SAVE_RESTORE and select
HIBERNATE_CALLBACKS directly. Also, drop the XEN_SAVE_RESTORE from the x86
xen config fragment.

No functional change intended with this clean-up.
