[U-Boot] [PATCH 08/11] drivers: net: aquantia: use SI and LI status in loop waiting for link up

[Alex Marginean]

In some cases the link on the system interface of the aquantia PHY comes up
after the link on line interface.  The link state loop only checks the line
side, which may result in first packet sent being lost.
Use aquantia_link_is_up instead, which checks both system and line side on
gen 2/3 PHYs to avoid losing the 1st packet.
