[PATCH 0/2] PCI/DPC: Improve register field accessing

["Ilpo Järvinen" <ilpo.jarvinen@linux.intel.com>]

This an alternative approach to the patch in:
  https://lore.kernel.org/linux-pci/20231010204436.1000644-7-helgaas@kernel.org/

It adds names to all the reason literals too (which makes it incompatible
with FIELD_GET() for the reason and ext_reason). When the reasons are
named instead of literals, it's very easy to understand the code just by
reading it (no need to lookup the meaning of those numbers from spec or
otherwise).

Also 0xfff4 the other patch missed is converted here.

Just let me know if I should, for example, base the additional changes
on top of that other change.

Ilpo Järvinen (2):
  PCI: Add PCI_EXP_DPC_* field details
  PCI/DPC: Use defines with register fields
