Ruslan Bukin 667c3fc0f6 Add PCI Express driver for the ARM Neoverse N1 System Development
Platform (N1SDP).

Neoverse N1 is a high-performance ARM microarchitecture designed
by the ARM Holdings for the server market.

The PCI part on N1SDP was shipped untested and suffers from some
integration issues.

For instance accessing to not existing BDFs causes System Error
(SError) exception. To mitigate this, the firmware scans the bus,
catches SErrors and creates a table with valid BDFs. That allows
us to filter-out accesses to invalid BDFs in this driver.

Also the root complex config space (BDF == 0) has an unusual
location in memory map, so remapping accesses to it is required.

Finally, the config space is restricted to 32-bit accesses only.

This was tested on the ARM boxes kindly provided by the ARM Ltd
to the DARPA CHERI Project.
