From: Matthew Gerlach <matthew.gerlach@intel.com>

This patchset enhances the definition of the Device Feature Header (DFH) used by
the Device Feature List (DFL) bus and then uses the new enhancements in a uart
driver.

Patch 1 updates the DFL documentation to provide the motivation behind the
enhancements to the definition of the DFH.

Patch 2 moves some of the DFH definitions to include/linux/dfl.h so that
they can be accessed by drivers outside of drivers/fpga.

Patch 3 adds the definitions for DFHv1.

Patch 4 defines and uses a DFHv1 parameter to provide a generic mechanism for
describing MSIX interrupts used by a particular feature instance.

Patch 5 adds a DFL uart driver that makes use of the new features of DFHv1.
