drm/amd/display: make flip_timestamp_in_us a 64-bit variable

[ Upstream commit 6fb12518ca58412dc51054e2a7400afb41328d85 ]

[Why]
This variable currently overflows after about 71 minutes. This doesn't
cause any known functional issues but it does make debugging more
difficult.

[How]
Make it a 64-bit variable.
