net/macb: Only adjust tx_clk on link change
The PHY state machine (in drivers/net/phy/phy.c) will unconditionally call phydev->adjust_link (macb_handle_link_change) when polling in the PHY_CHANGELINK state. As currently written, macb always ends up requesting a new tx_clk frequency in macb_handle_link_change. It is a waste of time to request a new tx_clk frequency if the link state hasn't changed, as the tx_clk will already be configured properly. Let's only request a new tx_clk clock frequency when necessary.
