[SeaBIOS] [PATCH 00/14] Clean up PCI BAR handling

[Kevin O'Connor]

This series adds some helper functions for working with PCI BARs (Base
Address Registers), and it then updates all the drivers to use these
helper functions.  The new helper functions perform sanity checks on
the BARs and make sure the appropriate pci command register flags are
enabled.  The existing driver code was inconsistent with these checks.

At the end of this series, the pci->have_driver flag is also
consistently set on any PCI device that there is a SeaBIOS driver for.
This will make sure SeaBIOS does not attempt to load an option rom for
a device that SeaBIOS already has a native driver for.
