drm/amd/display: Cursor lag with PSR1 eDP

Browse Source 
[Why]
On edp with psr1, we do not provide updates
of the cursor position regularly to firmware
like with PSR2. To send updates regularly,
the flag enable_sw_cntl_psr has to equal 1,
but cursor update should be provided
regularly to FW regardless of that flag.

[How]
Ensure that we always send cursor updates to
firmware when PSR version equals 1.
