commit 20829888caf411a4ac5a4349cbb013334e0b31de
Author: Bjoern A. Zeeb <bz@FreeBSD.org>
AuthorDate: Thu Jul 31 07:31:38 2025 +0000

drm: use LinuxKPI PCI functions rather than bsd native
LinuxKPI seems to provide everything needed here, which allows
us to remove the special casing for FreeBSD.
Switch from bsddev and FreeBSD native functions to LinuxKPI
variables and functions/macros; this will avoid conflicts with
upcoming additions to LinuxKPI.
