Make legacy_interrupt_line an Option
...
Drivers don't need to know the exact legacy_interrupt_pin in use.
Just if legacy interrupts are enabled and if so which
legacy_interrupt_line is used.

Only try to load drivers for endpoint functions
...
For bridge functions we don't have any existing drivers and we
currently panic if we would try to load a driver for them.

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.

Remove a lot of fields from PciHeader which are unlikely to be used
...
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.
