drm/xe/lrc: Remove leftover TODO/FIXME

There isn't anything to set for CTX_TIMESTAMP handling in the empty
LRC: that is set on every LRC init since it should always start from 0
rather than the value saved in the image after first submission.

The FIXME about perma-pinning also doesn't make much sense as we will
always going to pin the lrc and the GGTT mapping has nothing to do with
VM bind.

Nuke these leftover comments.
