qpci_pc_iomap() maps BARs one after the other, without padding. This
is wrong. PCI Local Bus Specification Revision 3.0, 6.2.5.1. Address
Maps: "all address spaces used are a power of two in size and are
naturally aligned". That's because the size of a BAR is given by the
number of address bits the device decodes, and the BAR needs to be
mapped at a multiple of that size to ensure the address decoding
works.
Fix qpci_pc_iomap() accordingly. This takes care of a FIXME in
ivshmem-test.
