drm/amd/display: Do not set optimized_require to false after plane disable
[ Upstream commit df36f6cf23ada812930afa8ee76681d4ad307c61 ]
[WHY]
The optimized_require flag is needed to set watermarks and clocks lower
in certain conditions. This flag is set to true and then set to false
while programming front end in dcn20.
[HOW]
Do not set the flag to false while disabling plane.
