6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

[ Upstream commit 56423871e9eef1dd069bddef895207fa5ce275fe ]

There is no firmware version dependency.  This also
enables sdma queue resets on all SDMA 6.x based
chips.
