[ Upstream commit f38129bb081758176dd78304faaee95007fb8838 ]
This reverts commit 80c6d6804f31451848a3956a70c2bcb1f07cfcb0.
The orignal commit was intended as a workaround to prevent underflow and
flickering when using one normal monitor and the other high refresh rate
monitor (> 120Hz).
This patch is being reverted in favour of a software solution to enable
SubVP+DRR
