    drm2: Update deprecation message
Update the deprecation message in the drm2 (aka legacy drm) drivers to point
    towards the graphics/drm-kmod ports for all architectures, not just amd64.
Only known user of drm2 is arm/tegra124 based boards. How
graphics/drm-kmod can help for these?
Or be more specific - drm2 allows me to hot-plug monitor to tegra based
board an use 2 scaled overlay planes (which is exactly whats I want for
   my application). Which alternative can you offer me?
Btw, as you can see, the maintenance cost of drm2 is close to zero and
the dev/drm2 code does not inherit with any of the major architectures.

   I think that the goal was only to mfc this to warn users before 12.2
is branched, maybe a direct commit to 12 would have been better.


No, the change is correct.
drm-legacy-kmod (the port) is going away, especially on FreeBSD 13,
since it is preventing updates to the FreeBSD VM subsystem.  I sent
an-email about this to a variety of lists about a week ago.
I do know that there are a few special users of drm2 in FreeBSD current,
I do not know how those are affected.  Since, on FreeBSD current, most
architectures can use drm-kmod, I believe it is good to point everyone
towards that ports, instead of pointing everyone except amd64 users to
drm-legacy-kmod.

  drm2 in src is only used for arm, so as Michal wrote in another email
the warning will be seen only for tegra users, the mfc'ed commit will
be seen by intel/amd ones though.


I still have to make a general change that can be MFCd. And pointing arm tegra users to drm-legacy-kmod is equally wrong.
