staging: fsl-dpaa2/eth: Set Tx timestamp support correctly
We used to set pass_timestamp parameter only for Tx
confirmation buffer layout config, when in fact MC
also looks at the Tx buffer layout when deciding whether
to enable Tx timestamping support or not.
Older versions of MC (< MC.1.x) enabled this support regardless
of user config, so the issue was hidden.
Copy the pass_timestamp setting to Tx buffer layout configuration.
