net/mlx5e: Remove the false indication of software timestamping support

BugLink: https://bugs.launchpad.net/bugs/1837257
[ Upstream commit 4765420439e758bfa4808392d18b0a4cb6f06065 ]

mlx5 driver falsely advertises support of software timestamping.
Fix it by removing the false indication.

Fixes: ef9814deafd0 ("net/mlx5e: Add HW timestamping (TS) support")
