xen/arm: lpae: Use the generic helpers to defined the Xen PT helpers
Currently, Xen PT helpers are only working with 4KB page granularity
and open-code the generic helpers. To allow more flexibility, we can
re-use the generic helpers and pass Xen's page granularity
(PAGE_SHIFT).
As Xen PT helpers are used in both C and assembly, we need to move
the generic helpers definition outside of the !__ASSEMBLY__ section.
Take the opportunity to prefix LPAE_SHIFT, LPAE_ENTRIES and
LPAE_ENTRY_MASK with XEN_PT_.
Note the aliases for each level are still kept for the time being so we
can avoid a massive patch to change all the callers.
