devices: pcie: modify PcieHostRootPort to PcieHostPort

Pcie upstream/downstream port will also have their related host port,
and their functionality should be similar with pcie host root port.
So I refactored PcieHostRootPort to PcieHostPort here, so that
pcie upstream/downstream port could use them later.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
