This commit adds support for the altp2m_get_domain_state HVMOP on ARM. All
code used in the command implementation already works on ARM, so no further
changes beyond moving the #ifdef are necessary.
This is commit 1/1 of the get_domain_state phase.

v6: Introduced this patch.
This commit can be squashed into the previous commit for the actual
submission if that would be preferred, but I thought it might be easier
to understand the command #ifdef gate approach by splitting this into a
separate patch.
