net: stmmac: fix channel TSO enable on resume

Browse Source 
Rather than configuring the channels depending on whether GSO/TSO is
currently enabled by the user, always enable if the hardware has TSO
support and the platform wants TSO to be enabled.

This avoids the channel TSO enable bit being disabled after a resume
when the user has disabled TSO features. This will cause problems when
the user re-enables TSO.

This bug goes back to commit f748be531d ("stmmac: support new GMAC4")
