net: usb: asix: ax88772: suspend PHY on driver probe

Browse Source 
After probe/bind sequence is the PHY in active state, even if interface
is stopped. As result, on some systems like Samsung Exynos5250 SoC based Arndale
board, the ASIX PHY will be able to negotiate the link but fail to
transmit the data.

To handle it, suspend the PHY on probe.
