libqos: Fix PC PCI endianness glitches

Browse Source 
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.
