xen_set_identity_and_remap() is used to prepare remapping of memory

new memory via a local variable which is passed to a subfunction
which in turn returns the new value for that variable.

Additionally the targeted maximum pfn is passed as a parameter to
sub functions.

Simplify that construct by using just global variables in the
source for that purpose. This will make things simpler when we need
those values later, too.

I'm not convinced this actually simplifies anything.

Perhaps I should have emphasised the last sentence a bit more. I really
need the global variables when deferring the remap operation.
