This still leaves create_aux_state_map() using physical number of layers for
the actual allocation. I toyed a little with this hoping to put it in front my
i965-to-isl work. In the end it looks to me that moving away from physical
is easier/cleaner once the conversion to isl is done. This prevents us from
addressing both isl-based and native slice table-based leaving just the
isl-based. Moreover in case of slice table-based we would need to calculate
a layer-number divider as the slice table itself stores depth as physical.

There are altogether 6 places calling get_num_phys_layers() in the end.
I think these document nicely all the locations we need to consider. How does
this sound?

That's fine with me.
