We had a stack size issue on DML, and we tried to fix it by moving some
of the local variables to some of the DML struct. In this process of
reducing the stack size, we sent some other patches that fixed the issue
reported by Stephen, and the below set of patches become unnecessary:

987949933127 drm/amd/display: reduce stack for dml32_CalculatePrefetchSchedule
8f08cd32b767 drm/amd/display: reduce stack for dml32_CalculateWatermarksMALLUseAndDRAMSpeedChangeSupport
5d526d124fe3 drm/amd/display: reduce stack for dml32_CalculateVMRowAndSwath
f6ceebcc7825 drm/amd/display: reduce stack for dml32_CalculateSwathAndDETConfiguration

For this reason, this patchset reverts all of the above patches.
