[PATCH 4/8] net: ethernet: ti: am65-cpsw: Add mac enable link function

[Siddharth Vadapalli]

Add function am65_cpsw_nuss_mac_enable_link() to invoke
am65_cpsw_enable_phy(), cpsw_ale_control_set(), am65_cpsw_qos_link_up()
and netif_tx_wake_all_queues() to prevent duplicate code. The above
set of function calls are currently invoked by the
am65_cpsw_nuss_mac_link_up() function. In a later patch in this series
meant for adding fixed-link support, even the am65_cpsw_nuss_mac_config()
function will invoke the same set of functions.
