Subject: [PATCH 20/20] net: stmmac: Move MAC Tx/Rx disabling to HW-setup antagonist

Since MAC Tx/Rx activity is enabled in the core hardware setup procedure
it would be logically correct to it disabled in the HW-setup antagonist -
stmmac_hw_teardown(). Let's do that to improve the driver code coherency
and thus readability.
