anv: fix incorrect VMA alignment for CCS main surfaces

Maybe finer way of dealing with this requirement would be to increase
the number of pdevice->memory.types[] to add a category for special
alignment cases.

Meanwhile this fixes the problem of CCS surface alignment and it's
probably not going to cause issues given the size of our address
space.
