[PATCH] xen/arm: p2m: fix pa_range_info for 52-bit pa range

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

Currently the pa_range_info for the 52-bit pa range advertizes that the
p2m root table consists of 8 concatenated tables at level 3, which does
not make much sense.
In order to support the 52-bit pa size with 4KB granule, the p2m root
table needs to be configured either as a single table at level -1 or
as 16 concatenated tables at level 0.
Since, currently there is not support for level -1, set the
root_order and sl0 fields of the corresponding pa_range_info according
to the second approach.
