subject: drm/nouveau/pmu/gm200-: use alternate falcon reset sequence
commit id: 4cdd2450bf739bada353e82d27b00db9af8c3001
kernels: 5.16 5.15 and 5.10

1d2271d2fb85e54bfc9630a6c30ac0feb9ffb983 got backported to a bunch of
kernel versions, which wasn't really intentional from nouveaus side. I
assume this happened because autosel picked it up due to the
"Reported-by" tag? Anyway, It actually requires
4cdd2450bf739bada353e82d27b00db9af8c3001 as well in order to not
regress systems. One bug report can be found here:
https://gitlab.freedesktop.org/drm/nouveau/-/issues/149

Users did test that applying 4cdd2450bf739bada353e82d27b00db9af8c3001
on top fixes the problems.

We still want to figure out what to do with 5.4 and older, because the
fix doesn't apply there, so we will either request a revert or send
modified patches.

Thanks

A revert is fine if you want to send me that.
