A small fix to remove a legacy workaround that discovered still more newly introduced bugs.

From https://marc.info/?l=openbsd-cvs&m=169087658917322&w=2

In inteldrm the function intel_dp_wait_source_oui() can be called before last_oui_write is set and so the code requires a positive initial jiffies value. On linux this is the case for 64bit systems (but not for 32bit) and because of this idiosyncracy this bug was introduced in upstream intel code. Instead of adding another OpenBSD specific quirk to drm code alter our jiffies initalisation.
