[PATCH net-next v5 3/7] net: stmmac: don't rely on lynx_pcs presence to check for a PHY

[Romain Gantois <romain.gantois@bootlin.com>]

From: Maxime Chevallier <maxime.chevallier@bootlin.com>

When initializing attached PHYs, there are some cases where we don't expect
any PHY to be connected. The logic uses conditions based on various local
PCS configuration, but also calls-in phylink_expects_phy() via
stmmac_init_phy(), which is enough to ensure we don't try to initialize a
PHY when using a Lynx PCS, as long as we have the phy_interface set to a
802.3z mode and are using inband negociation.

Drop the lynx check, making the stmmac generic code more pcs_lynx-agnostic.
