Few missing #define are the cause of a compile failure with
XEN_TARGET_ARM=arm and XEN_COMPILE_ARM=arm (for example in the case of a
native compilation). This patch fill the gaps.

Can we make all new public interfaces explicitly sized, please?
Cheers,
Tim.

Yes please, and explicitly sized in a way which is compatible with 64
bits too (i.e. u64 here rather than u32 even though PC happens to be 32
bits).
I'd quite like to do a sweep of the existing interfaces and arrange this
to be the case even for existing interfaces when used on new
architectures. I expect that will be an enormous amount of churn though
-- possibly not worth it.
Ian.

Introduce an empty implementation of the arch specific ARM functions in
xc_dom_arm.c.
Also provide empty implementations of xc_domain_save, xc_domain_restore
and xc_hvm_build_target_mem when CONFIG_HVM or CONFIG_MIGRATE are not
set.
