virtio_set_modern_bar is an external interface that backend virtio driver can call to initialize the PCI capabilities and PCI bars defined in the virtio 1.0 spec. The following are done in the function: - 5 PCI capabilities are added to the PCI configuration space of the virtio PCI device. (common/isr/device_specific/notify/cfg_access) - A 64-bit MMIO bar is allocated to accommodate the registers defined in the 4 PCI capabilities. (cfg_access capability does not require MMIO.) - If use_notify_pio is true, a PIO notify capability is added to the PCI configuration space and a PIO bar is allocated for it accordingly.
