Shuffle lines around so that the assignments in mfn_to_xen_entry()
occur in the same order as the bits are declared in lpae_pt_t.
This makes it easier to see which ones are never given a value.
No change in behaviour.
Also fix a minor comment typo.

Ensure that every relevant bit is given an explicit value.
This has no effect on the generated code, but makes it
a little easier to follow.

Changed in v2: merged create_32mb_mappings() and create_2mb_mappings()
into create_mappings(). A side-effect is to fix the bug in v1 for
ARM64 systems with <4GB RAM.
Changed in v3: Ensure that the granularity variabl
