From: Mikita Lipski <mikita.lipski@amd.com>

[ Upstream commit af1f2b19fd7d404d299355cc95930efee5b3ed8b ]

[why]
For dual eDP when setting the new settings we need to set
command version to DMUB_CMD_PSR_CONTROL_VERSION_1, otherwise
DMUB will not read panel_inst parameter.
[how]
Instead of PSR_VERSION_1 pass DMUB_CMD_PSR_CONTROL_VERSION_1
