[PATCH net-next 2/2] net: stmmac: Don't rely on the PHY for flow-control testing

[Maxime Chevallier <maxime.chevallier@bootlin.com>]

For flow-control testing in loopback mode, we don't need to ask what the
PHY is currently using as pause/asym settings. The PHY is no longer
involved in selftest, we rely strictly on MAC loopback. We therefore
only need to know if the MAC supports Symmetric pause for the test, as
we exercise both TX and RX pause support in the selftest.

Remove phydev requirement for flowcontrol selftest as well as the
AsymPause requirement.

With that, we can also drop the linux/phy.h include.
