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.

This patch allows qpci_iomap to return the size of the
BAR mapping that it created, to allow driver applications
(e.g, ahci-test) to make determinations about the suitability
or the mapping size, or in the specific case of AHCI, how
many ports are supported by the HBA.

The libqos implementation of io_read{b,w,l} and io_write{b,w,l} hooks
was relying on qtest_mem{read,write}() respectively. With d81d410 (usb:
improve ehci/uhci test) this resulted in assertion failures on ppc hosts:
ERROR:tests/usb-hcd-ehci-test.c:78:ehci_port_test: assertion failed: ((value & mask) == (expect & mask))
ERROR:tests/usb-hcd-ehci-test.c:128:pci_uhci_port_2: assertion failed: (pcibus != NULL)
ERROR:tests/usb-hcd-ehci-test.c:150:pci_ehci_port_2: assertion failed: (pcibus != NULL)
qtest_read{b,w,l,q}() and qtest_write{b,w,l,q}() had been introduced
as endian-safe replacement for qtest_mem{read,write}() in I2C in
872536b (qtest: Add MMIO support). Use them for PCI as well.
