gpy_update_interface() returns early in case the PHY is internal or
connected via USXGMII. In this case the gigabit master/slave property
as well as MDI/MDI-X status also won't be read which seems wrong.
Always read those properties by moving the logic to retrieve them to
gpy_read_status().

Fixes: fd8825cd8c6fc ("net: phy: mxl-gpy: Add PHY Auto/MDI/MDI-X set driver for GPY211 chips")
Fixes: 311abcdddc00a ("net: phy: add support to get Master-Slave configuration")
