[PATCH 5.15.y 1/3] ravb: Remove setting of RX software timestamp

[Sasha Levin <sashal@kernel.org>]

From: Gal Pressman <gal@nvidia.com>

[ Upstream commit 277901ee3a2620679e2c8797377d2a72f4358068 ]

The responsibility for reporting of RX software timestamp has moved to
the core layer (see __ethtool_get_ts_info()), remove usage from the
device drivers.
