When booting U-Boot in crosvm, the virtual machine emulates a PCI cam device, not the PCI-E 'ecam' device normally seen on e.g. QEMU. This PCI device can be supported with only trivial changes to the ecam driver. Instead of adding a completely new driver which is identical besides the initialization step, add support for the PCI version to the existing driver.
