UPDATING: bump __FreeBSD_version for drm-kmod/nvidia-drm vs. LinuxLPI

Both drm-kmod and nvidia-drm were updated to keep compiling and/or
working after the latest LinuxKPI PCI changes. Some of what should
have worked for a long time but did not or conflicted was hidden
behind native PCI calls instead of using LinuxKPI. We cleaned this
up. Bump __FreeBSD_version so that users will get the updated packages.
