Don't try to fetch BARs unless there is a matching driver
...
Fetching BARs will temporarily invalidate them, which could cause
crashes if a driver happens to access it at the same time. As we
don't yet use a single pcid instance, we don't know which devices
have a driver attached or not. As such approximate this as the set
of devices for which the current pcid instance would load a driver.

Remove fetch_header from pcid_interface
...
Most things are already stored in SubdriverArguments and the couple of
things that aren't may change over time and thus should be read again
each time they are accessed, while fetch_header would receive a fixed
copy from pcid.

Some of these are removed with PCIe while many others only need to be
used by the firmware to initialize the PCI bridges. If we ever need
them anyway, we can always add them back, but for now it improves
readability.
