device/pci: untangle struct device and device_t
This patch uses struct device explicitly for the ramstage functions as that's the actual type it's working on. Additionally, the declarations for types and functions are fully exposed so that compliation units don't have to guard certain functions from use because it's being compiled for multiple stages.
