hw/block/nvme: move msix table and pba to BAR 0
In the interest of supporting both CMB and PMR to be enabled on the same
device, move the MSI-X table and pending bit array out of BAR 4 and into
BAR 0.
This is a simplified version of the patch contributed by Andrzej
Jakowski (see [1]). Leaving the CMB at offset 0 removes the need for
changes to CMB address mapping code.
