VHE: Add helper to get attributes of a stage 1 va range.
This patch adds a new helper function mm_get_mode, similar to
mm_vm_get_mode, to get the attributes of a stage 1 va range. This is
useful to be able to get memory attributes of a EL0 partitions va range
for example. This patchset modifies the existing function
mm_vm_get_attrs to take flags as an argument so that the same function
can work with stage 1 tables as well. Also added helper function to
convert attributes to mode for stage 1 similar to stage 2 helper
function.
