xen/arm: Introduce helpers to get/set an MFN from/to an LPAE entry

The new helpers make it easier to read the code by abstracting the way to
set/get an MFN from/to an LPAE entry. The helpers are using "walk" as the
bits are common across different LPAE stages.

At the same time, use the new helpers to replace the various open-coding
place.
