[PATCH 3/3] drm/amd/display: Use USEC_PER_SEC

[Christophe JAILLET]

Use USEC_PER_SEC instead of defining an equivalent local 'us_in_sec'.

Signed-off-by: Christophe JAILLET <christophe.jaillet at wanadoo.fr>
---
NOT compile tested. Because of some BROKEN in KConfig files.
Some header may be missing for USEC_PER_SEC!
