[PATCH 14/20] drm/amd/display: Fix inconsistent timestamp type

[Pavle Kotarac]

From: Angus Wang <angus.w...@amd.com>

[WHY]
An unsigned int timestamp variable is assigned with an unsigned
long long value. Also, the assignment directly converts the
tick value to us without using built-in get elapsed time function.

[HOW]
Cast the assigned value correctly and also use built-in function
to get the timestamp in the unit we want.
