libqos: allow qpci_iomap to return BAR mapping size

Browse source 
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.
