drm/amd/display: Fix timer_per_pixel unit error
[ Upstream commit 23e55639b87fb16a9f0f66032ecb57060df6c46c ]
[why]
The units of the time_per_pixel variable were incorrect, this had to be
changed for the code to properly function.
[how]
The change was very straightforward, only required one line of code to
be changed where the calculation was done.
