[PATCH 5.14 206/432] drm/amd/display: Fix timer_per_pixel unit error

[Greg Kroah-Hartman]

From: Oliver Logush <oliver.logush@xxxxxxx>

[ 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.
