xen: Convert page_to_mfn and mfn_to_page to use typesafe MFN

Browse Source 
Most of the users of page_to_mfn and mfn_to_page are either overriding
the macros to make them work with mfn_t or use mfn_x/_mfn because the
rest of the function use mfn_t.

So make page_to_mfn and mfn_to_page return mfn_t by default. The __*
version are now dropped as this patch will convert all the remaining
non-typesafe callers.

Only reasonable clean-ups are done in this patch. The rest will use
_mfn/mfn_x for the time being.

Lastly, domain_page_to_mfn is also converted to use mfn_t given that
most of the callers are now switched to _mfn(domain_page_to_mfn(...)).
