Bug description:
[ Impact ]
* The KV260 is currently unable to boot, this will allow the board to boot.
* Kernel boot testing of 5.15.0-1032.36 failed on the KV260. The new kernel
is installed but the system does not come back up after a reboot. Console logs
show that there is a soft lockup.
[ Test Plan ]
* Normal certification and kernel regression testing will be run on all GM'd
platforms. The failure was catestrophic and was easily caught.
[ Where problems could occur ]
* Xilinx has changes to the dmaengine driver that have not been upstreamed,:
specifically adding support for cyclic dma mode. There is a risk that these
non-upstreamed changes have not been tested with this change.
[ Other Info ]
* BugLink: https://bugs.launchpad.net/bugs/2072456
* Upstream state in original commit was incorrect.
* Upstream commit "dma: xilinx_dpdma: Fix locking"
